The compounds of general formula I are prepared by methods which are known in principle, particularly using processes derived from peptide chemistry (cf. for example Houben-Weyl, Methoden der Organischen Chemie, Vol. 15/2). The amino protecting groups used may be those described in Houben-Weyl, Methoden der Organischen Chemie, Vol. 15/1, of which urethane protecting groups such as the fluorenylmethoxycarbonyl, phenylmethoxycarbonyl or tert.-butyloxycarbonyl group are preferred. Any functional groups present in the groups R

and/or A of the compounds of general formula I or in the precursors thereof are additionally protected by suitable protecting groups in order to prevent side reactions (cf. for example: G. B. Fields et al., Int. J. Peptide Protein Res. 35, 161 (1990); T. W. Greene, Protective Groups in Organic Synthesis). Examples of side-chain-protected amino acids of this kind include, in particular, Arg(NO

), Arg(Mtr), Arg(di-Z), Arg(Pmc) Lys(Boc), Lys(Z), Orn(Boc), Orn(Z), Lys(Cl-Z) which are commercially obtainable, possibly in the form of derivatives. Particular care should be taken to ensure that so-called orthogonal combinations of protecting groups are used to protect the α-amino and the side chain amino group, e.g.:

Instead of protecting amino groups in the side chain, amino acids or derivatives thereof which carry precursor functions and in particular are substituted by nitro or cyano in the side chain, such as 5-o-cyanonorvalin may also be used.




The basic functions in the side chains of α-amino acids which are not commercially obtainable and which are characterised, for example, by (aminoiminomethyl) groups, may be protected in the same way as is used for protecting the side chains of arginine and its derivatives (cf. also M. Bodanszky, “Peptide Chemistry”, Springer-Verlag, 1988, p. 94-97); protecting groups which are particularly suitable for the (aminoiminomethyl)- group are the p-toluenesulphonyl, mesitylene sulphonyl—(Mts), methoxytrimethylphenylsulphonyl—(Mtr), 2,2,5,7,8-pentamethylchroman-6-sulphonyl—(Pmc), pentachlorophenoxycarbonyl- and nitro-protecting groups.




For the actual coupling, the methods known from peptide chemistry are used (see Houben-Weyl, for example, Methoden der Organischen Chemie, Vol. 15/2). It is preferable to use carbodiimides such as dicyclohexylcarbodiimide (DCC), diisopropylcarbodiimide (DIC) or ethyl-(3-dimethylaminopropyl)-carbodiimide, O-(1H-benzotriazol-1-yl)N,N-N′,N′-tetramethyluroniumhexafluorophosphate (HBTU) or tetrafluoroborate (TBTU) or 1H-benzotriazol-1-yloxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (BOP). By the addition of 1-hydroxybenzotriazole (HOBt) or 3-hydroxy-4-oxo-3,4-dihydro-1,2,3-benzotriazine (HOObt) racemisation may additionally be suppressed, if desired, or the reaction rate may be increased. The couplings are normally carried out with equimolar amounts of the coupling components and the coupling reagent in solvents such as dichloromethane, tetrahydrofuran, acetonitrile, dimethylformamide (DMF), dimethylacetamide (DMA), N-methylpyrrolidone (NMP) or mixtures thereof and at temperatures between −30 and +30° C., preferably between −20 and +20° C. If necessary, N-ethyl-diisopropylamine (DIEA) is preferred as an additional auxiliary base (Hünig base).

Bodanszky, “Principles of Peptide Synthesis”, Springer-Verlag 1984, p. 21-27) was used as another coupling method for the synthesis of compounds of general formula I. The “mixed anhydride method” is preferred, in the variant according to Vaughan (J. R. Vaughan Jr., J. Amer. Chem.Soc. 73, 3547 (1951)), in which the mixed anhydride is obtained from the optionally N


2


-protected α-amino acid which is to be coupled, and the mono-isobutylcarbonate, using isobutylchlorocarbonate in the presence of base such as 4-methylmorpholine or 4-ethylmorpholine. The preparation of this mixed anhydride and the coupling with amines are carried out in a one-pot process using the above-mentioned solvents at temperatures between −20 and +20° C., preferably between 0 and +20° C.




Any protecting groups present in the side chains of α-amino acid partial structures are finally cleaved, after the formation of the N- and C-terminally substituted amino acid derivative, with suitable reagents which are also known from the literature in principle, specifically arylsulphonyl and hetarylsulphonyl protecting groups, preferably by acidolysis, i.e. by the action of strong acids, preferably trifluoroacetic acid, nitro- and arylmethoxycarbonyl protecting groups are preferably cleaved by hydrogenolysis, e.g. using hydrogen in the presence of palladium black and with glacial acetic acid as solvent. If the substrate contains functions which are sensitive to hydrogenolysis, e.g. halogen atoms such as chlorine, bromine or iodine, a phenylmethanol or hetarylmethanol function or some other benzyl heteroatom bond, particularly a benzyl-oxygen bond, the nitro group may also be cleaved non-hydrogenolytically, e.g. with zinc/2N trifluoroacetic acid (cf. also A. Turan, A. Patthy and S. Bajusz, Acta Chim. Acad. Sci. Hung, Tom. 85 (3), 327-332 [1975]; C.A. 83, 206526y [1975]), with tin(II)-chloride in 60% aqueous formic acid (see also: SUNSTAR KK, JA-A-3271-299), with zinc in the presence of acetic acid (cf. also: A. Malabarba, P. Ferrari, G. Cietto, R. Pallanza and M. Berti, J. Antibiot. 42 (12), 1800-1816 (1989)) or excess aqueous 20% titanium(III)-chloride in aqueous methanol and in the presence of aqueous ammonium acetate buffer at 24° C. (see also: R. M. Freidinger, R. Hirschmann and D. F. Veber, J. Org. Chem. 43 (25), 4800-4803 [1978]).




Any precursor functions which may be present in the side chain of the α-amino acid may also subsequently be converted by hydrogenolysis into the desired amino functions; nitroalkyl groups yield aminoalkyl groups under conditions which will be familiar to the chemist, whilst the cyano group is converted into the aminomethyl group.




Alternatively, nitrile functions may also be reduced with complex hydrides which are selective in relation to other critical functions contained in the molecule, particularly amide groups (cf. also: J. Seyden-Penne, “Reductions by the Alumino- and Borohydrides in Organic Synthesis”, VCH Publishers Inc., 1991, p. 132ff.), e.g. with sodium borohydride in methanol and in the presence of cobalt(II)-chloride, with sodium borohydride in tetrahydrofuran in the presence of trifluoroacetic acid or with tetrakis-(n-butyl)-ammonium borohydride in dichloromethane; the reduction of aliphatic nitro function to the primary amino-function is also possible with sodium borohydride in the presence of tin(II)-chloride or copper(II)-acetylacetonate, without affecting the carboxamide groups present in type I compounds (see also: J. Seyden-Penne, ibid. p. 137ff.).

— group, frequently in the presence of auxiliary bases, especially alkali metal carbonates such as sodium- or potassium carbonate, or tertiary amines, preferably N-ethyl-diisopropylamine or triethylamine.




The amino acids of general formula I modified according to the invention contain at least one chiral centre. If the group A is also chiral, the compounds may occur in the form of two diastereomeric pairs of antipodes. The invention includes the individual isomers as well as the mixtures thereof.




The diastereomers are separated on the basis of their different physicochemical properties, e.g. by fractional crystallisation from suitable solvents, by high pressure liquid or column chromatography using chiral or preferably achiral stationary phases.




Racemates covered by general formula I may be separated, for example, by HPLC on suitable chiral stationary phases (e.g. Chiral AGP, Chiralpak AD). Racemates which contain a basic or acidic function can also be separated by means of the diastereomeric optically active salts which are formed on reacting with an optically active acid, e.g. (+)- or (−)-tartaric acid, (+)- or (−)-diacetyl tartaric acid, (+)- or (−)-monomethyltartrate or (+)-camphor sulphonic acid or an optically active base such as (R)-(+)-1-phenylethylamine, (S)-(−)-1-phenylethylamine or (S)-brucine.




According to a conventional process for separating isomers, the racemate of a compound of general formula I is reacted with one of the above-mentioned optically active acids or bases in equimolar amounts in a solvent and the crystalline, diastereomeric, optically active salts obtained are separated on the basis of their different solubilities. This reaction may be carried out in solvents of any kind provided that they are sufficiently different in terms of the solubility of the salts. Preferably, methanol, ethanol or mixtures thereof are used, e.g. in a ratio by volume of 50:50. Then each of the optically active salts is dissolved in water, neutralised with a base such as sodium carbonate or potassium carbonate, sodium hydroxide solution or potassium hydroxide solution, and in this way the corresponding free compound is obtained in the (+)- or (−)-form.




The (R)-enantiomer alone or a mixture of two optically active diastereomeric compounds coming within the scope of general formula I may also be obtained by carrying out the syntheses described above with a suitable reaction component in the (R)-configuration.




The starting materials of general formulae VII, IX, X, X′, XI, XII, XIII, XV, XVa, XVII, XXI, XXII required to synthesis the compounds of general formula I as well as the amino acids used are commercially available or may be prepared by methods known from the literature.




Compounds of general formula VIII wherein Z denotes the group NR

and those of general formula VIII′ wherein X denotes the oxygen atom may be obtained from commonly available starting materials using methods familiar to peptide chemists.




Isocyanates of general formula XII can easily be obtained from α-amino acid derivatives of general formula VIII′ wherein R

denotes a hydrogen atom and the other groups are as hereinbefore defined, or from the hydrochlorides thereof by reacting with phosgene, diphosgene or triphosgene in the presence of pyridine (see also: J. S. Nowick, N. A. Powell, T. M. Nguyen and G. Noronha, J. Org. Chem. 57, 7364-7366 [1992]).




Carboxylic acids of general formulae XIV and XVI may be obtained from the corresponding carboxylic acid esters by saponification, preferably in the presence of lithium hydroxide.




The carboxylic acids of general formula XVIII are obtained by saponifying corresponding carboxylic acid esters which are in turn prepared from suitable secondary amines, 4-aryl-4-oxobutanoic acid esters and formaldehyde by Mannich reaction.




Compounds of general formula XIX may be obtained from suitable 4-oxobutanoic acids and amines of general formula X using conventional methods.




The intermediate compounds of general formula XX come under general formula I and are thus within the scope of the present application. These compounds may be obtained, for example, using processes a) to h) described herein.




The compounds of general formula I may be converted into their physiologically acceptable salts with inorganic or organic acids, particularly for pharmaceutical applications. Examples of suitable acids for this purpose include hydrochloric acid, hydrobromic acid, phosphoric acid, nitric acid, sulphuric acid, methanesulphonic acid, p-toluenesulphonic acid, acetic acid, fumaric acid, succinic acid, lactic acid, mandelic acid, malic acid, citric acid, tartaric acid or maleic acid.




Moreover, if the new compounds of formula I thus obtained contain an acid function, for example a carboxy group, they may if desired be converted into the addition salts thereof with inorganic or organic bases, more particularly for pharmaceutical use, into the physiologically acceptable addition salts thereof. Bases which may be considered include, for example, sodium hydroxide, potassium hydroxide, ammonia, cyclohexylamine, dicyclohexylamine, ethanolamine, diethanolamine and triethanolamine.




The new compounds of general formula I and the physiologically acceptable salts thereof have CGRP-antagonistic properties and exhibit good affinities in CGRP-receptor binding studies. The compounds exhibit CGRP-antagonistic properties in the pharmacological test systems described hereinafter.




The following experiments were carried out to demonstrate the affinity of compounds of general formula I for human CGRP-receptors and their antagonistic properties:

After the cell number has been determined the cells are homogenised using an Ultra-Turrax and centrifuged for 10 minutes at 3000×g. The supernatent is discarded and the pellet is recentrifuged and resuspended (1 ml/1000000 cells) in Tris-buffer (10 mM Tris, 50 mM NaCl, 5 mM MgCl


2


, 1 mM EDTA, pH 7.40), enriched with 1% bovine serum albumin and 0.1% bacitracin. The homogenate is frozen at −80° C. The membrane preparations are stable for more than 6 weeks under these conditions.




After thawing, the homogenate is diluted 1:10 with assay buffer (50 mM Tris, 150 mM NaCl, 5 mM MgCl


2


, 1 mM EDTA, pH 7.40) and homogenised for 30 seconds with an Ultra-Turrax. 230 μl of the homogenate are incubated at ambient temperature for 180 minutes with 50 pM of


125


I-Iodotyrosyl-Calcitonin-Gene-Related Peptide (Amersham) and increasing concentrations of the test substances in a total volume of 250 μl. Incubation is ended by rapid filtration using GF/B-glass fibre filters treated with polyethyleneimine (0.1%) by means of a cell harvester. The protein-bound radioactivity is measured using a gammacounter. The non-specific binding is defined as the radioactivity bound after the presence of 1 μM of human CGRP-alpha during incubation.




The concentration binding curves are analysed using a computer-aided non-linear curve adaptation.




The compounds of general formula I show IC


50


values≦10000 nM in the test described.




B. CGRP-Antagonism in SK-N-MC-cells




SK-N-MC-cells (1 million cells) are washed twice with 250 μl of incubation buffer (Hanks' HEPES, 1 mM 3-isobutyl-1-methylxanthine, 1% BSA, pH 7.4) and pre-incubated at 37° C. for 15 minutes. After the addition of CGRP (10 μl) as agonist in increasing concentrations (10


−11


to 10


−6


M) or additionally of substance in 3 to 4 different concentrations, incubation is continued for a further 15 minutes.




Intracellular cAMP is then extracted by the addition of 20 μl of 1M HCl and centrifugation (2000×g, 4° C. for 15 minutes). The supernatants are frozen in liquid nitrogen and stored at −20° C.




The cAMP contents of the samples are determined by radioimmunoassay (Amersham) and the pA


2


-values of antagonistically acting substances are determined graphically.




The compounds of general formula I display CGRP-antagonistic properties in a dosage range between 10


−11


and 10


−5


M in the in vitro test model described.




In view of their pharmacological properties the compounds of general formula I and the salts thereof with physiologically acceptable acids or bases are thus suitable for acute and prophylactic treatment of headache, particularly migraine and cluster headaches. Moreover, the compounds of general formula I also have a beneficial effect on the following diseases: non-insulin-dependent diabetes mellitis (NIDDM), cardiovascular diseases, skin diseases, particularly thermal and radiation-induced skin damage including sunburn, inflammatory diseases, e.g. inflammatory joint diseases (arthritis), inflammatory lung diseases, allergic rhinitis, asthma, diseases which involve excessive vasodilation and resultant reductions in circulation, e.g. shock and sepsis, as well as morphine tolerance. In addition, the compounds of general formula I have the effect of alleviating pain in general.




The dosage needed to achieve such effects is appropriately 0.0001 to 3 mg/kg of body weight, preferably 0.01 to 1 mg/kg of body weight, by intravenous or subcutaneous route, and 0.01 to 10 mg/kg of body weight, preferably 0.1 to 10 mg/kg of body weight, when administered orally, nasally or by inhalation, in each case 1 to 3 times a day.




For this purpose, the compounds of general formula I prepared according to the invention may be formulated, optionally in combination with other active substances, such as antiemetics, prokinetics, neuroleptics, antidepressants, neurokinin-antagonists, anti-convulsants, histamine-H1-receptor antagonists, antimuscarinics, β-blockers, α-agonists and α-antagonists, ergot alkaloids, mild analgesics, non-steroidal antiphlogistics, corticosteroids, calcium-antagonists, 5-HT


1D


-agonists or other antimigraine agents, together with one or more inert conventional carriers and/or diluents, e.g. corn starch, lactose, glucose, microcrystalline cellulose, magnesium stearate, polyvinylpyrrolidone, citric acid, tartaric acid, water, water/ethanol, water/glycerol, water/sorbitol, water/polyethyleneglycol, propyleneglycol, cetylstearylalcohol, carboxymethylcellulose or fatty substances such as hard fat or suitable mixtures thereof, to produce conventional galenic preparations such as plain or coated tablets, capsules, powders, suspensions, solutions, metering aerosol or suppositories.




Thus, additional active substances which may be considered for the above-mentioned combinations include, for example, meloxicam, ergotamine, dihydroergotamine, metoclopramide, domperidon, diphenhydramine, cyclizine, promethazine, chlorpromazine, dexamethasone, flunarizine, dextropropoxyphene, meperidine, propranolol, nadolol, atenolol, clonidine, indoramine, carbamazepine, phenytoin, valproate, amitryptilin, lidocaine, diltiazem or sumatriptan and other 5-HT


1D


-agonists such as naratriptan, zolmitriptan, avitriptan, rizatriptan and eletriptan. The dosage for these active substances is appropriately 1/5 of the lowest dose normally recommended up to 1/1 of the normally recommended dosage, i.e. 20 to 100 mg of sumatriptan, for example.




The invention further relates to the use of the compounds of general formula I as valuable auxiliary agents for the production and purification (by affinity chromatography) of antibodies and, after suitable radiolabelling, e.g. by direct labelling with


125


I or


131


I or by tritiation of suitable precursors for example by replacing halogen atoms with tritium, in RIA- and ELISA assays and as diagnostic or analytical aids in neurotransmitter research.

Preparation of compounds of general formula:











1-(4-amino-3,5-dibromo-D-phenylalanyl)-4-(4-pyridinyl)piperazine




A mixture of 39 g (0.089 mol) of 4-amino-3,5-dibromo-N-[(1,1-dimethylethoxy)carbonyl]-D-phenylalanine, 35.7 g (0.111 mol) of TBTU, 12.3 g (0.089 mol) of HOBt, 14.5 g (0.089 mol) of 1-(4-pyridinyl)-piperazine and 19.6 ml of (0.111 mol) of DIEA in 1000 ml of tetrahydrofuran was stirred overnight at room temperature. The reaction mixture was extracted once with saturated aqueous saline solution and twice with saturated aqueous sodium hydrogen carbonate solution. The combined aqueous phases were extracted once with tetrahydrofuran and the combined tetrahydrofuran phases were washed once with saturated aqueous saline solution. After drying the organic phase with sodium sulphate it was evaporated down in vacuo and the residue was taken up in ethyl acetate. The ethyl acetate phase was filtered after drying again and evaporated down in vacuo. 52.5 g of the intermediate compound were obtained as a viscous oil, which was then mixed with 300 ml of methylene chloride and 80 ml of trifluoroacetic acid and stirred overnight at room temperature. The reaction mixture was evaporated down in vacuo, the residue formed was triturated with ether. 45.8 g (72% of theory) of the desired product were obtained as a white amorphous solid.

The organic phase was washed once with saturated aqueous sodium hydrogen carbonate solution and after drying evaporated down in vacuo. The residue was recrystallised twice from isopropanol (22.6g; 22% of theory), the mother liquors were combined, evaporated down and purified by column chromatography (MN-silica gel 60, Macherey-Nagel, 70-230 mesh ASTM; eluant: ethyl acetate/methanol=8/2 (v/v)). A further 28.0 g (26.7% of theory)of the desired end product were obtained. Total yield: 49% of theory.

2


-[4-(2-chlorophenyl)-1-piperazinyl]carbonyl]-D-phenylalanine in a mixture of 30 ml of methanol and 20 ml of water were added 0.25 g (10.0 mmol) of lithium hydroxide and the mixture was then stirred for 3 hours at room temperature. After the addition of 2.0 g (50 mmol) of sodium hydroxide the mixture was diluted with 50 ml of water. The reaction mixture was stirred for 15 minutes in an ultrasound bath, then stirred overnight at room temperature and evaporated down in vacuo. The residue was mixed with 100 ml of water and the aqueous phase was extracted twice with 50 ml of ether. By the addition of 2 M aqueous hydrochloric acid the aqueous phase was adjusted to a pH of 3-4 and extracted three times with ethyl acetate. The combined ethyl acetate phases were washed once with water, then dried and evaporated down in vacuo. 1.6 g (58% of theory) of a yellowish-brown oil were obtained.

1-[4-[4-(dimethylamino)butyl]phenyl]-piperazine-dihydrochloride




a) N,N-dimethyl-4-fluoro-γ-oxobenzenebutanoic acid amide




To a solution of 30.5 g (0.155 Mol) of 4-fluoro-γ-oxobenzenebutanoic acid in 470 ml tetrahydrofuran, 35.0 g (0.216 Mol) of N,N′-carbonyldiimidazole was added with stirring and at room temperature and held at room temperature for a further 2.5 hours. Then, 13.7 g (0.304 Mol) of dimethylamine was added under strong external cooling by means of an ice-ethanol mixture. After the mixture had stood at room temperature for 12 hours, the solvent was removed in vacuo, the residue was divided between dichloromethane and 10% aqueous citric acid solution, the organic phase was dried over sodium sulphate and once again evaporated down in vacuo. After purification by column chromatography (eluant: ethyl acetate) on silica gel the crude product yielded 30.22 g (87% of theory) of colourless crystals of




R


f


=0.31 (eluant: ethyl acetate/glacial acetic acid 99.99/0.01).

b) N,N-dimethyl-γ-oxo-4-[4-(phenylmethyl)-1-piperazinyl]-benzenebutanoic acid amide




The mixture of 33.48 g (0.15 Mol) of N,N-dimethyl-4-fluoro-γ-oxobenzenebutanoic acid amide, 29.6 g (0.168 Mol) of 1-(phenylmethyl)piperazine and 6 ml of DIEA was refluxed for 6 hours. Another 30 g (0.17 Mol) of (phenylmethyl)piperazine was added, and the mixture was refluxed for a further 7 hours. The mixture was taken up in a little dichloromethane, and purified by column chromatography on silica gel, using dichloromethane/methanol/conc. ammonia 99/1/0.5 for elution. The residue obtained from the appropriate fractions was stirred with diisopropylether, the formed crystals were then recrystallised from ethanol. 42.22 g (74% of theory) of colourless crystals were obtained, R

Colourless, amorphous substance of Rf 0.37 (eluant: ethyl acetate/methanol 50/50/0.5 v/v/v).




B. PREPARATION OF THE FINAL COMPOUNDS




EXAMPLE 1




Preparation of compounds of general formula:











1-[N-[4-(1,3-dihydro-2(2H)-oxobenzimidazol-1-yl)-1-piperidinyl]carbonyl]-3,5-dibromo-D-tyrosyl]-4-(4-pyridinyl)-piperazine (No. 83)




A mixture of 2 g (3.44 mmol) of 3,5-dibromo-N

-[4-(1,3-dihydro-2(2H)-oxobenzimidazol-1-yl)-1-piperidinyl]-carbonyl]-D-tyrosine, 0.59 g (3.6 mmol) of 1-(4-pyridinyl)-piperazine, 1.27 g (3.96 mmol) of TBTU, 0.47 g (3.44 mmol) of HOBt, 0.7 ml (3.96 mmol) of DIEA and 100 ml tetrahydrofuran was stirred overnight at ambient temperature. The reaction mixture was extracted once with saturated aqueous saline solution, twice with saturated aqueous sodium hydrogen carbonate solution and again with saturated aqueous saline solution. The organic phase was dried, evaporated down in vacuo and the crude product was then purified by column chromatography (MN-silica gel 60, Macherey-Nagel, 70-230 mesh ASTM, eluant: ethyl acetate/methanol=9/1/(v/v/)). 550 mg (22% of theory) of an amorphous solid were obtained.

-(1.1-dimethylethoxycarbonyl)-L-lysyl]-4-(4-pyridinyl)piperazine, 0.35 g (1.10 mmol) of TBTU, 0.14 g (1.0 mmol) of HOBt, 0.2 ml (1.10 mmol) of DIEA and 100 ml of dimethylformamide was stirred overnight at ambient temperature. The reaction mixture was evaporated down in vacuo and divided between methylene chloride and saturated aqueous sodium hydrogen carbonate solution. The organic phase was then extracted once with saturated aqueous sodium hydrogen carbonate solution and with water, dried and evaporated down in vacuo. The crude product was purified by column chromatography (MN-silica gel 60, Macherey-Nagel, 70-230 mesh ASTM, eluant: ethyl acetate/methanol=8/2 (v/v/)), taken up in 30 ml of methylene chloride and stirred with 3 ml of trifluoroacetic acid for 3 hours at ambient temperature. The reaction mixture was evaporated down in vacuo, the residue was triturated with ether and the obtained amorphous solid (0.43 g, 37% of theory) was suction filtered.

EXAMPLE 4




Preparation of compounds of general formula:











1-[4-amino-3,5-dibromo-N-[4-(1,3,3a,4,5,6,7,7a-octahydro-2(2H)-oxobenzimidazol-1-yl)-1-piperidinyl]carbonyl]-D-phenylalanyl]-4-(4-pyridinyl)-piperazine (No. 91)




A mixture of 0.35 g (2.1 mmol) of CDT, 1.0 g (1.4 mmol) of 4-(1,3,3a,4,5,6,7,7a-octahydro-2(2H)-oxobenzimidazol-1-yl)-piperidine, 0.5 ml of (2.8 mmol) of DIEA and 100 ml of tetra-hydrofuran was stirred for 1 hour whilst cooling with ice and then for 30 minutes at ambient temperature. With stirring 0.46 g (1.75 mmol) of 1-(4-amino-3,5-dibromo-D-phenylalanyl)-4-(4-pyridinyl)piperazine and 0.32 ml of (1.8 mmol) of DIEA were added and refluxed for 3 hours. The reaction mixture was diluted with 100 ml of ethyl acetate and the organic phase was washed twice with aqueous saturated sodium hydrogen carbonate solution. The combined aqueous phases were then extracted once with ethyl acetate/tetrahydrofuran=1/1 (v/v) and the combined organic phases were washed once with saturated aqueous saline solution. After drying the organic phase and eliminating the solvent in vacuo the residue was purified by column chromatography (MN-silica gel 60, Macherey-Nagel, 70-230 mesh ASTM, eluant: ethyl acetate/methanol=9/1 (v/v)). 120 mg (12% of theory) of a colourless foam were obtained.

-[(1,1-dimethylethoxy)carbonyl]-L-lysyl]-4-(4-pyridinyl)-piperazine in methanol were added 2 ml of methanol saturated with hydrogen chloride and the mixture was stirred overnight at ambient temperature. The reaction mixture was mixed with ethyl acetate until the hydrochloride was totally precipitated and the precipitate formed was filtered off. After washing the precipitate with water it was purified by column chromatography (MN-silica gel 60, Macherey-Nagel, 70-230 mesh ASTM, eluant: ethyl acetate/methanol/conc. aqueous ammonia=5/5/0.5 (v/v/v)). 0.38 g (55% of theory) of an amorphous solid were obtained.

-[(1.1-dimethylethoxy)carbonyl]-L-lysyl]-4-(4-pyridinyl)-piperazine in 50 ml of tetrahydrofuran within 60 minutes. The reaction mixture was stirred for 1 hour at 0° C., then stirred for 2 hours at ambient temperature, mixed with a tetrahydrofuran solution of 0.24 g (1.6 mmol) of (3-methoxyphenyl)-ethanamine, refluxed for 3 hours and stirred overnight at ambient temperature. After elimination of the solvent in vacuo the residue was purified by column chromatography (MN-silica gel 60, Macherey-Nagel, 70-230 mesh ASTM, eluant: FM1). The resulting intermediate compound was stirred in a mixture of 5 ml of trifluoroacetic acid and 80 ml of dichloromethane overnight, the solvent was eliminated in vacuo and the residue triturated with ether. 709 mg (43% of theory) of the desired compound as an amorphous solid.

-[(1,1-dimethylethoxy)carbonyl]-L-lysyl]-4-(4-pyridinyl)-piperazine and the mixture was stirred for 30 minutes at 0° C. and for a further 30 minutes at ambient temperature. After the addition of 0.47 g (1.75 mmol) of 1-(2,3-dichlorophenyl)piperazine-hydrochloride and 0.25 ml of triethylamine the reaction mixture was refluxed for 5 hours and after cooling mixed with 70 ml of saturated aqueous sodium hydrogen carbonate solution. The organic phase was separated off, the aqueous phase was extracted twice with 50 ml of tetrahydrofuran. The combined organic phases were washed with saturated aqueous saline solution, dried over magnesium sulphate, filtered and evaporated down in vacuo. The residue was triturated with ether, suction filtered and then stirred for 2 hours with a mixture of 50 ml of dichloromethane and 5 ml of trifluoroacetic acid. After evaporation of the reaction mixture in vacuo and trituration of the residue with ether, 0.8 g (47% of theory) of an amorphous solid are left.
