Abstract
The present invention provides glycopeptide antibiotic derivative compounds. These derivative compounds possess antibacterial activity against a wide variety of bacteria, including activity against vancomycin-resistant isolates. Methods of making and using these glycopeptide antibiotic derivative compounds are also provided.
Description

BACKGROUND OF THE INVENTION
New improved antibiotics are continually in demand, particularly for the treatment of human diseases. Increased potency, expanded spectrum of bacterial inhibition, increased in vivo efficacy, and improved pharmaceutical properties are some of the goals for improved antibiotics.
In the search for new antibiotics, structural modification of known antibiotics is attempted whenever possible. The glycopeptide antibiotics have such complex structures that even small changes are difficult. Furthermore, it is difficult to predict the effect these changes will make in the antimicrobial and physiological properties. Processes for modifying known antibiotics and the new active derivatives made by such processes, therefore, continue to be of great importance.
Previously, N-alkyl and N-acyl derivatives of the glycopeptides vancomycin, A51568A, A51568B, M43A and M43D have been prepared (U.S. Pat. Nos. 4,639,433, 4,643,987, and 4,698,327). Several of these compounds exhibited microbiological activity, including activity against vancomycin-resistant isolates. Nicas et al., Antimicrobial Agents and Chemotherapy, 33(9):1477-1481 (1989). In addition, European Patent Application Publication No. 0435503, published Jul. 3, 1993, describes certain N-alkyl and N-acyl derivatives of the A82846 glycopeptides, factors A, B, and C.
The formula I compounds of this invention are new members of the glycopeptide group of antibiotics. These new compounds are derivatives of known glycopeptide antibiotics that include vancomycin (U.S. Pat. 3,067,099); A82846A, A82846B, and A82846C (U.S. Pat. 5,312,738, European Patent Publication 256,071 A1); PA-42867 factors A, C, and D (U.S. Pat. 4,946,941 and European Patent Publication 231,111 A2); A83850 (U.S. Pat. No. 5,187,082); avoparcin (U.S. Pat. 338,786 and U.S. Pat. 4,322,343); actinoidin, also known as K288 (J. Antibiotics Series A 14:141 (1961); helevecardin (Chem. Abstracts 110:17188 (1989) and Japanese Patent Application 86/157,397); galacardin (Chem. Abstracts 110:17188 (1989) and Japanese Patent Application 89/221,320); and M47767 (European Patent Publication 339,982). The references listed above which describe these glycopeptides are incorporated herein by reference.
Enterococci are important human pathogens. Infections caused by enterococci are generally difficult to treat. Glycopeptides, such as vancomycin and teicoplanin, have become important therapies in the treatment of infections due to enterococci. However, strains of Enterococcus faecium and E. faecalis have recently been isolated that are resistant to vancomycin and teicoplanin. Leclercq et al., "Plasmid Mediated Resistance to Vancomycin and Teicoplanin in Enterococcus Faecium," The New England Journal of Medicine, 319(3):157-161 (1988), and Uttley et al., "Vancomycin-Resistant Enterococci," Lancet, 1:57-58 (1988). The isolates were also found to be resistant to other antibiotics. A recent survey found 7.9% of Enterococci in United States hospitals are now vancomycin resistant. "Nosocomial Enterococci Resistant to Vancomycin" Morbidity and Mortality Weekly Report 42 (30):597-598 (1993). In addition to their broad activity against gram-positive organisms, many of the glycopeptide compounds of this invention also exhibit improved antimicrobial activity against vancomycin-resistant isolates.

Formula I compounds that are prepared from A83850A or A83850B can be prepared from the reduced forms of these compounds. The reduced forms of compounds A83850A or A83850B are produced according to the method described in U.S. Pat. No. 5,187,082, which is incorporated herein by reference.
The compounds of this invention are prepared by reacting a formula II compound with an aldehyde to form an intermediate Schiff's base, which is subsequently reduced with a metal borohydride to give the desired N-alkyl amine.
In the first method of making the compounds of this invention, hereinafter Method A (described in Examples 1 and 2), the reaction for the formation of the Schiff's base is carried out under an inert atmosphere, such as nitrogen or argon, in a polar solvent, such as dimechylformamide (DMF) or methanol (MeOH), or a mixture of polar solvents, such as a mixture of dimethylformamide and methanol, at a temperature of about 25.degree. C. to about 100.degree. C. The reaction is preferably carried out at a temperature from about 60.degree. C. to about 70.degree. C. for 30 minutes to 2 hours in a mixture of dimethylformamide and methanol, or in methanol. The intermediate Schiff's base is then reduced, preferably without isolation, to produce the corresponding N-alkyl derivative(s). The reduction of the Schiff's base can be effected using a chemical reducing agent such as a metal borohydride, for example, sodium borohydride or sodium cyanoborohydride. The reduction reaction can be carried out in a polar organic solvent, such as dimethylformamide, methanol, or a mixture of polar solvents, such as a mixture of dimethylformamide and methanol. The reduction reaction can be carried out at a temperature of about 25.degree. C. to about 100.degree. C. for 1 to 5 hours. The reduction reaction is preferably carried out using an excess of sodium cyanoborohydride in a mixture of dimethylformamide and methanol or in methanol at about 60.degree. C. to about 70.degree. C. for 1 to 2 hours. Method A is preferable for benzylic aldehydes.
In a second method of making compounds of this invention, hereinafter Method B (described in Example 3), the formation of the Schiff's base is carried out under an inert atmosphere, such as nitrogen or argon, in the presence of the reducing agent, sodium cyanoborohydride, in a polar solvent, such as dimethylformamide, methanol, or a mixture of polar solvents, such as a mixture of dimethylformamide and methanol, at a temperature of about 25.degree. C. to about 100.degree. C. for 1 to 5 hours. The reaction is preferably carried out at a temperature from about 60.degree. C. to about 70.degree. C. for 1 to 2 hours in a mixture of dimethylformamide and methanol. Method B is preferable for non-benzylic aldehydes.
In a third method of making compounds of this invention, hereinafter Method C (described in Example 4), the formation of the Schiff's base is carried out a) under an inert atmosphere, such as nitrogen or argon, b) in the presence of the reducing agent, such as a metal borohydride, with sodium cyanoborohydride being most preferred, or a homogenous or heterogeneous catalytic hydrogenation agent(s), such as Crabtree's catalyst, Wilkinson's catalyst, palladium on carbon, platinum on carbon, or rhodium on carbon, c) in a polar solvent, such as dimethylformamide, methanol, or a mixture of polar solvents, such as a mixture of dimethylformamide and methanol, and d) at a temperature of about 25.degree. C. to about 100.degree. C. The reaction is preferably carried out at a temperature from about 60.degree. C. to about 70.degree. C. in methanol. The reaction is allowed to continue for about 20 to about 28 hours, at which time the reaction mixture is adjusted to about pH 7.5 to about pH 10, with a pH of about 9.0 being preferred. The pH adjustment halts the reaction. Because the product is marginally soluble in polar solvents, the solvent of the reaction can be exchanged to an alcohol such as ethanol, butanol, or isopropanol, with isopropanol being preferred, to allow for precipitation of the product. Method C is a preferred method of this invention in view of the increased product yield provided by this method. Another advantage of this reaction scheme is the increased ratio of preferred product (products substituted at the amino group of the sugar denoted as R.sup.1 in Formula II compounds) to other products (products that are substituted at the amino groups of substitutents denoted as R and/or R.sup.3 of the Formula II compounds). By allowing the reaction to proceed for an extended period of time, such as 20 to 28 hours, products that are monosubstituted at positions denoted as R and R.sup.3 in the Formula II compounds are converted to disubstituted forms, making the preferred monosubstituted derivative easier to isolate.
The products of the reaction, obtained from either Method A, B, or C can be purified by preparative reverse-phase HPLC utilizing Waters C18 Nova-Pak columns with ultraviolet light (UV; 235 nm or 280 nm) detection. A 30 minute gradient solvent system consisting of 95% aqueous buffer/5% CH.sub.3 CN at time=0 minutes to 20% aqueous buffer/80% CH.sub.3 CN at time=30 minutes is typically used, where the aqueous buffer is either TEAP (0.5% aqueous triethylamine adjusted to pH=3 with phosphoric acid) or TFA (0.1% trifluoroacetic acid overall concentration).
HPLC analysis of the reaction mixtures and final purified products can be accomplished utilizing a Waters C18 MicroBonda-Pak column (typically 3.9.times.300 mm steel) or Waters Nova-pak C18 RCM column (8.times.100 mm) with UV (235 nm or 280 nm) detection. A 30 minute gradient solvent system consisting of 95% aqueous buffer/5% CH.sub.3 CN at time=0 minute to 20% aqueous buffer/80% CH.sub.3 CN at time=30 minutes is typically used, where the aqueous buffer is either TEAP (0.5% aqueous triethylamine adjusted to pH=3 with phosphoric acid) or TFA (0.1% trifluoroacetic acid overall concentration).
The ratio of the aldehyde to the formula II compound and the reaction conditions determines the products of the reaction. The monosubstituted derivatives are those derivatives where a hydrogen atom of the amino group at position R.sup.1 in formula II is replaced by one of the substituents listed above for formula I. When using Methods A or B, described above, the formation of monosubstituted derivatives substituted at the amino group of the amino sugar at position R.sup.1 in the formula II compounds is favored by using a slight excess of aldehyde, a shorter reaction time, and a lower temperature. As noted above, Method C favors the formation of the monosubstituted derivative. The monosubstituted derivative is preferred. A large excess of the aldehyde favors the formation of disubstituted and trisubstituted derivatives of the formula II compounds. The disubstituted derivatives are the derivatives where a hydrogen atom at two of the locations selected from the amino group at position R.sup.3, and the amino group of the amino sugars designated as R or R.sup.1 in formula II, are replaced by the reduced aldehyde moiety. The trisubstituted derivatives are the derivatives where a hydrogen atom at three of the locations selected from the amino group at position R.sup.3, and the amino group of the amino sugars designated as R or R.sup.1 in formula II, are replaced by the reduced aldehyde moiety.
A further object of this invention are those compounds that are monosubstituted at the amino group of the amino sugar at position R of formula II, when such an amino sugar is present at this position, or at the amino group at position R.sup.3 of formula II. Further, the disubstituted and trisubstituted derivatives referred to above are also objects of this invention. These derivatives are useful in the treatment of bacterial infections. Methods A, B, and C (described above, and in the Examples) can be used to produce the monosubstituted, disubstituted and trisubstituted derivatives.
Preferably, Method D, described in Example 5, is used to produce those derivatives that are monosubstituted at the amino group at position R.sup.3 of formula II. Method D is also preferred for The synthesis of disubstituted derivatives substituted at the amino group of the amino sugar designated as R.sup.1 in the formula II compounds, and at the amino group at position R.sup.3 in the formula II compounds.
Preferably, Method E, as described in Example 5, is used to produce those disubstituted derivatives that are substituted at the amino groups of the amino sugars designated as R.sup.1 and R in the formula II compounds. Method E is also preferably used to produce the trisubstituted derivatives. The trisubstituted compounds can be formed when there is an amino sugar at the position designated as R in the formula II compounds.

The formula I compounds have also shown in vivo antimicrobial activity against experimentally-induced infections in laboratory animals. When two doses of test compound were administered to mice experimentally infected with the test organism, the activity observed was measured as an ED.sub.50 value (effective dose in mg/kg to protect 50% of the test animals: see W. Wick et al., J. Bacteriol. 81, 233-235 (1961)). ED.sub.50 values observed for illustrative compounds are given in Table 4.

One important aspect of the antimicrobial activity of many of the formula I compounds is their activity against vancomycin-resistant enterococci. This activity of illustrative in Table 5, which summarizes a comparison of the activity of illustrative compounds against representative vancomuycin-resistant and vancomycin-susceptible enterococci (Enterococcus faecium and Enterococcus faecalis, mean geometric MIC (mcg/mL)), as determined using the standard broth micro-dilution assay.

A number of the lactic acid bacteria including all Leuconostocs, all Pediococci, and some Lactobacilli, are intrinsically resistant to vancomycin. With the increased use of vancomycin, infections due to these bacteria have been reported with increasing frequency in immunocompromised patients (Handwerger et al., Reviews of Infectious Disease 12:602-610 (1990); Ruoff et al., Journal of Clinical Microbiology 26:2062-2068 (1988)). One important aspect of the antimicrobial activity of the formula I compounds is their activity against the vancomycin-resistant lactic acid bacteria. The compounds of the present are useful in inhibiting the growth of vancomycin- resistant lactic bacteria such as Leuconostoc, Pedicocci, and Lactobacilli and thus, controlling opportunistic infections by this group of bacteria. This activity is illustrated in Table 6, which summarizes a comparison of the activity of illustrative compounds against representative vancomycin-resistant lactic acid bacteria (Pedicoccus acidilacti Pedicoccus pentosaceus, Leuconostoc lactis, Leuconostoc mesenteroides, Leuconostoc pseudomesenteroides, Leuconostoc citreum, and Lactobacillus confusus, mean geometric MIC (mcg/mL)), as determined using a standard agar dilution assay on brain-heart infusion agar.

Pharmaceutical formulations of the formula I compounds are also part of this invention, Thus, the compound, preferably in the form of a pharmaceutically acceptable salt, can be formulated for oral or parenteral administration for the therapeutic or prophylactic treatment of bacterial infections.
For example, the compound can be admixed with conventional pharmaceutical carriers and excipients and used in the form of tablets, capsules, elixirs, suspensions, syrups, wafers, and the like. The compositions comprising a formula I compound will contain from about 0.1 to about 90% by weight of the active compound, and more generally from about 10 to about 30%. The compositions may contain common carriers and excipients, such as corn starch or gelatin, lactose, sucrose, microcrystalline cellulose, kaolin, mannitol, dicalcium phosphate, sodium chloride, and alginic acid.
Disintegrators commonly used in the formulations of this invention include croscarmellose, microcrystalline cellulose, corn starch, sodium starch glycolate and alginic acid.
Tablet binders that can be included are acacia, methylcellulose, sodium carboxymethylcellulose, poly-vinylpyrrolidone (Povidone), hydroxypropyl methylcellulose, sucrose, starch and ethylcellulose.
Lubricants that can be used include magnesium stearate or other metallic stearates, stearic acid, silicone fluid, talc, waxes, oils and colloidal silica.
Flavoring agents such as peppermint, oil of wintergreen, cherry flavoring or the like canalso be used.
It may be desirable to add a coloring agent to make the dosage form more attractive in appearance or to help identify the product.
For intravenous (IV) use, a water soluble form of the antibiotic can be dissolved in one of the commonly used intravenous fluids and administered by infusion. Such fluids as, for example, physiological saline, Ringer's solution, or 5% dextrose solution can be used.
For intramuscular preparations, a sterile formulation of a suitable soluble salt form of the compound, for example the hydrochloride saly, can be dissolved and administered in a pharmaceutical diluent such as pyrogen-free water (distilled), physiological saline or 5% glucose solution. A suitable insoluble form of the compound may be prepared and administered as a suspension in an aqueous base or a pharmaceutically acceptable oil base, for example, an ester of a long chain fatty acid such as ethyl oleate.
For oral use, a sterile formulation of a suitable salt form of the antibiotic, for example, the hydrochloride salt, formulated in a diluent such as distilled or deionized water, is particularly useful.
Alternatively, the unit dosage form of the antibiotic can be a solution of the antibiotic, preferably in its salt form, in a suitable diluent in sterile, hermetically sealed ampoules. The concentration of the antibiotic in the unit dosage may vary, for example, from about 1 percent to about 50 percent depending on the particular form of the antibiotic and its solubility and the dose desired by the physician.
In a further aspect, this invention provides a method for treating infectious diseases, especially those caused by Gram-positive microorganisms, in animals. The compounds of this invention are particularly useful in treating infections caused by methicillin-resistant staphylococci. Also, the compounds are useful in treating infection due to enterococci. Examples of such diseases are severe staphylococcal infections, for example, staphylococcal endocarditis and staphylococcal septicemia. The animal may be either susceptible to, or infected with, the microorganism. The method comprises administering to the animal an amount of a formula I compound which is effective for this purpose. In general, an effective amount of a formula I compound is a dose between about 0.5 and about 100 mg/kg. A preferred dose is from about 1 to about 60 mg/kg of active compound. A typical daily dose for an adult human is from about 50 mg to about 5 g.
In practicing this method, the antibiotic can be administered in a single daily dose or in multiple doses per day. The treatment regimen may require administration over extended periods of time, for example, for several days or for from one to six weeks. The amount per administered dose or the total amount administered will depend on such factors as the nature and severity of the infection, the age and general health of the patient, the tolerance of the patient to the antibiotic and the microorganism or microorganisms in the infection.
A convenient method of practicing the treatment method is to administer the antibiotic via intravenous infusion. In this procedure a sterile formulation of a suitable soluble salt of the antibiotic is incorporated in a physiological fluid, such as 5% dextrose solution, and the resulting solution is infused slowly IV. Alternatively, the piggy-back method of IV infusion can also be used.





In order to illustrate more fully the operation of this invention, the following examples are provided, but are not to be construed as a limitation on the scope of the invention.
EXAMPLE 1
METHOD A
Preparation of Compound 2
A mixture of A82846B tricetate, (2.25 g, 1,27 mmol, 1.0 equivalents (eq)) in 1:1 DMF/methanol (140 mL) under an atmosphere of argon was treated with 4-biphenylcarboxaldehyde (331 mg, 2.12 mmol, 1.7 eq). The resulting mixture was heated to 70.degree. C. and maintained as such for 1.75-2 hours. The solution was then treated with sodium cyanoborohydride (554 mg, 8.83 mmol, 6.9 eq). Heating at 70.degree. C. was continued for an additional 1.75-2 hours after which the reaction mixture was cooled to room temperature, concentrated in vacuo, diluted with water (150 mL), and lyophilized to give a solid.
The solid was purified by preparative reverse-phase high performance liquid chromatography (HPLC) using a Waters 3.times.(40 .times.100 mm) C18 Nova-Pak cartridge with Waters C18 Nova-pak guard insert and utilizing TEAP buffer system. The analytical method for analysis was: 0.2% TEA/phosphoric acid (TEAP), pH=3, the gradient system at time 0 was 5% CH.sub.3 CN/94.9% H.sub.2 O with 0.2% TEAP held constant and at 20 minutes was 60% CH.sub.3 CN/39.8% H.sub.2 O with 0.2% TEAP held constant. The UV wavelength used was 235 nm and the flow rate was 2 ml/minute. Analysis was done using a Waters Nova-pak C18 guard (8.times.100 mm) with a Nova-pak C18 guard insert. It is necessary to desalt the product after reverse phase purification when this HPLC method is used.
Desalting was accomplished by adding the purified product to 5-10 ml of H.sub.2 O. 1 N HCl was added dropwise with stirring to dissolve the sample. The pH at this point was approximately 1-3. The pH of the solution was then raised to 8.2 with 1 N NaOH. A white solid precipitated out of solution. The mixture was cooled, filtered, and dried under vacuum at room temperature for 8-15 hours to give the zwitter ion (or neutral compound) of the desired product, compound 2 (p-phenylbenzyl-A82846B), (1.02 g, 45%).
EXAMPLE 2
Preparation of Compound 4
A mixture of A82846B triacetate (1.5 g, 0.848 mmol, 1.0 eq) in methanol (100 mL) under an atmosphere of argon was treated with p-phenoxybenzaldehyde (298 mg, 1,51 mmol, 1.8 eq). The resulting mixture was heated to reflux and maintained as such for 2 hours. The solution was then treated with sodium cyanoborohydride (326 mg, 5.18 mmol, 6.1 eq). Heating at reflux was continued for an additional 2 hours after which the reaction mixture was cooled to room temperature and evaporated to dryness in vacuo.
The product was purified by reverse-phase HPLC with a TFA buffer. The analytical method for analysis was accomplished by using a Waters Nova-pak C18 RCM column (8.times.100 mm) with a Nova-pak C18 guard insert, eluting with a 2.0 ml/minute linear gradient of 15% acetonitrile/0.1% TFA at time zero to 80% acetonitrile/0.1% TFA at 15 minutes. The fractions containing the products were detected by ultraviolet scan at 235 nm. The organic solvent of the desired fractions was removed and the mixture was lyophilized to a white solid to give 0.618 mg of p-phenoxybenzyl.A82846B compound 4.tris(trifluroacetate) salt (20% yield). No desalting or further purification was necessary. This method is also especially useful in the preparation of Compound 2 wherein phenylbenzaldehyde is one of the starting materials.
EXAMPLE 3
Method B
Preparation of Compound 176
A mixture of A82846B.triacetate (280 mg, 0.157 mmol, 1.0 eq) in 1:1 DMF/methanol (30 mL) was treated with 8-phenyloctanal (59 mg, 0.29 mmol, 1.8 eq) and sodium cyanoborohydride (60 mg, 0.95 mmol, 6.1 eq). The resulting mixture was heated, under an atmosphere of nitrogen, to 70.degree. C. and maintained as such for 1 hour. The reaction mixture was then cooled to room temperature and concentrated in vacuo to give a residue. Purification of the product was accomplished by reverse-phase preparative HPLC utilizing a Waters 2.times.(40.times.100 mm) C18 Nova-Pak cartridge with Waters C18 Nova-Pak guard insert. Elution was accomplished with a 30 minute linear gradient (time=0 minutes 95% TEAP (0.5% aqueous triethylamine adjusted to pH=3 with phosphoric acid)/5% CH.sub.3 CN to t=30 minutes 20% TEAP/80% CH.sub.3 CN) with a flow rate of 40 mL/minute and UV detection at 280 nm. The desired fraction was concentrated in vacuo then desalted with a Waters Sep-Pak cartridge as described below. This afforded compound 176 in 22% yield (60 mg).
The resulting compound was desalted as follows. A Waters Sep-Pak cartridge was pre-wet with methanol (2-3 column volumes) then conditioned with water (2-3 column volumes). The sample, dissolved in a minimum volume of water, was loaded onto the Sep-Pak column which was then washed with water (2-3 column volumes) to remove the unwanted salts. The product was then eluted with an appropriate solvent system, typically 1:1 CH.sub.3 CN/H.sub.2 O, CH.sub.3 CN, and/or methanol. The organic solvent component was removed in vacuo and the resulting aqueous solution lyophilized to give the final product.
EXAMPLE 4
Preparation of Compound 229
A three liter 3-necked flask was fitted with a condenser, nitrogen inlet and overhead mechanical stirring apparatus. The flask was charged with pulverized A82846B acetate salt (20.0 g, 1.21.times.10.sup.-3 mol) and methanol (1000 mL) under a nitrogen atmosphere. 4'-chlorobiphenylcarboxaldehyde (2.88 g, 1.33.times.10.sup.-2 mol, 1.1 eq.) was added to this stirred mixture, followed by methanol (500 mL). Finally, sodium cyanoborohydride (0.84 g, 1.33.times.10.sup.-2 mol, 1.1 eq.) was added followed by methanol (500 mL). The resulting mixture was heated to reflux (about 65.degree. C.).
After 1 hour at reflux, the reaction mixture attained homogeneity. After 25 hours at reflux, the heat source was removed and the clear reaction mixture was measured with a pH meter (6.97 at 58.0.degree. C.). 1 N NaOH (22.8 mL) was added dropwise to adjust the pH to 9.0 (at 54.7.degree. C.). The flask was equipped with a distillation head and the mixture was concentrated under partial vacuum to a weight of 322.3 grams while maintaining the pot temperature between 40-45.degree. C.
The distillation head was replaced with an addition funnel containing 500 mL of isopropanol (IPA). The IPA was added dropwise to the room temperature solution over 1 hour. After approximately 1/3 of the IPA was added, a granular precipitate formed. The remaining IPA was added at a faster rate after precipitation had commenced. The flask was weighed and found to hold 714.4 grams of the IPA/methanol slurry.
The flask was re-equipped with a still-head and distilled under partial vacuum to remove the remaining methanol. The resulting slurry (377.8 g) was allowed to chill in the freezer overnight. The crude product was filtered through a polypropylene pad and rinsed twice with 25 mL of cold IPA. After pulling dry on the funnel for 5 minutes, the material was placed in the vacuum oven to dry at 40.degree. C. A light pink solid (22.87 g (theory =22.43 g)) was recovered. HPLC analysis versus a standard indicated 68.0% weight percent of Compound 229 (4-[4-chlorophenyl]benzyl-A82846B] in the crude solid, which translated into a corrected crude yield of 69.3%.
The products of the reaction were analyzed by reverse-phase HPLC utilizing a Zorbax SB-C18 column with ultraviolet light (UV; 330 nm) detection. A 20 minute gradient solvent system consisting of 95% aqueous buffer/5% CH.sub.3 CN at time=0 minutes to 40% aqueous buffer/60% CH.sub.3 CN at time=20 minutes was used, where the aqueous buffer was TEAP (5 ml CH.sub.3 CN, 3 ml phosphoric acid in 1000 ml water).

The following procedure is referred to herein as Method D. A 100 ml 3 necked flask was fitted with a condenser and charged with 0.75 g (0.45 mmol) of A82846B, 0.197 g (2 eqs., 0.91 mmol) of 4'-chloro-biphenylcarboxaldehyde, 0.086 g (3 eqs., 1.4 mmol) sodium cyanoborohydride, 25 ml methanol and 25 ml H.sub.2 O. The mixture was heated to reflux and monitored by HPLC. After 6.5 hours, heating was stopped and the mixture transferred to a single-neck recovery flask. Concentration in vacuo afforded 1.02 g of off-white solids. This material was subjected to preparative chromatography for isolation of the desired components.
The products of the reaction were analyzed by reverse-phase HPLC utilizing a Zorbax SB-C18 column with ultraviolet light (UV; 230 nm) detection. A 20 minute gradient solvent system consisting of 95% aqueous buffer/5% CH.sub.3 CN at time=0 minutes to 40% aqueous buffer/60% CH.sub.3 CN at time=20 minutes was used, where the aqueous buffer was TEAP (5 ml CH.sub.3 CN, 3 ml phosphoric acid in 1000 ml water). The resulting material was held for five minutes and then returned to 95% aqueous buffer/5% CH.sub.3 CN. The reaction yielded 9.19% starting material (A82846B), 14.93% Compound 229, 21.22% Compound 252, 10.53% Compound 253, 25.89% Compound 254, and 4.99% Compound 255.
In order to enrich for the formation of compounds 253, and 255, the following procedure, which is referred to herein as Method E, was utilized. A 100 ml, necked flask was fitted with a condenser and nitrogen inlet. The flask was charged with 1 g (0.61 mmol) of A82846B, 0.394 g (3 eqs., 1.82 mmol) of 4'-chloro-biphenylcarboxaldehyde, 0.114 g (3 eqs., 1.8 mmol) sodium cyanoborohydride and 50 ml methanol). The mixture was heated to reflux and allowed to stir under nitrogen overnight. After 25 hours at reflux, heating was stopped and the mixture was transferred to a single-neck recovery flask and concentrated n vacuo. 1.42 g of off-white solids were recovered. Using the analytical HPLC method described above in this Example it was determined that the reaction yielded 5.19% of Compound 229, 25.14% of Compound 253, 10.15% of Compound 254, and 42.37% of Compound 255.
Preparative chromatography was used to isolate Compounds 252, 253, 254, 255. A 200 mg aliquot of either the preparation from Method D or E, above, was dissolved in 2.5 ml of 1:1 AcOH:methanol and injected into a waters Prep 3000 preparative chromatography unit with a Waters Nova-Pak C-18 reverse phase column (3.times.40mm .times.100mm) using ultraviolet light (UV; 235 nm) detection. A 45 minute gradient solvent system consisting of 15% acetonitrile/75% water/10% of a 1% TFA aqueous buffer at time=0 minutes to 85% acetonitrile/15% water/10% of a 1% TFA aqueous buffer at time=45 minutes was used with a flow rate of 40 ml/min. Elution of the material was observed via a strip chart recorder. Fractions were collected. All fractions containing Compound 229 and/or mixtures were discarded. Fractions containing the pure components (Compounds 252, 253, 254, and 255) were combined, concentrated to remove organic solvents and lyophilized to afford the TFA salts of the derivatives. After re-analysis by HPLC to confirm purity, samples were submitted for FAB mass spectroscopy. Identification of the compounds was based upon the fragmentation patterns observed in the FAB spectra.
