Patent Application
20060229310
This invention is directed to antibacterial compounds, processes for making them and intermediates used in the processes, compositions containing them, and methods for treatment of bacterial infections using them.

3-cyclohexylpropionaldehyde (1 g) in dichloromethane (30 mL) at 25° C. was treated with 2-trimethylsilylthiazole (1.2 g), stirred for 6 hours, treated with THF (30 mL) and 1M TBAF in THF (8 mL), stirred for 2 hours, and concentrated. The concentrate in ethyl was washed with saturated NaHCO3, water, and brine, and dried (MgSO4), filtered, and concentrated. The concentrate was flash chromatographed with 5-20% ethyl acetate/hexanes.
A mixture of ethyl 3-methyl-4-bromobenzoate (32 g) in diethyl ether (450 mL) at −78° C. was treated with 1M lithium aluminum hydride in THF (190 mL), stirred for 1.5 hours, treated with brine, and filtered. The filtrate was washed with 1M HCl and brine, and dried (Na2SO4), filtered, and concentrated.
A mixture of EXAMPLE 9 (25 g) in ethanol (300 mL) was treated with concentrated sulfuric acid (12 mL), stirred at reflux for 3 days, concentrated to 50 mL, treated with sodium carbonate to pH 8, and extracted with ethyl acetete. The extract was dried (Na2SO4), filtered, and concentrated.
A mixture of EXAMPLE 10 (23 g), bis(pinicolato)diboron (32 g), potassium carbonate (40 g) in 1,4-dioxane was treated with [1,1′-bis(diphenylphosphine)ferrocene]dichloropalladium dichloromethane (4.67 g), stirred for 6 hours at 90° C., and concentrated to 80 mL. The concentrate was treated with ethyl acetate (500 mL), washed with water, 1M HCl, and brine, and dried (Na2SO4), filtered, and concentrated. The concentrate was flash chromatographed on silica gel with 10-30% ethyl acetate/hexanes.
An alcohol (one of EXAMPLES 1-8) (0.321 mmol) in tert-butanol (0.2 mL) at 25° C. was treated with 1M potassium tert-butoxide in THF (0.32 mL), stirred for 1 hour, treated with EXAMPLE (75 mg) in tert-butanol (5 mL) and of potassium iodide (105 mg), stirred at 50° C. for 1 hour, and concentrated. A mixture of the concentrate and lithium hydroxide monohydrate (45 mg) in 3:2 THF/water (2 mL) at 25° C. was stirred for 72 hours, treated with saturated aqueous NH4Cl and acetic acid and extracted with dichloromethane. The extract was concentrated, and the concentrate was purified by reverse phase HPLC.
The foregoing is merely illustrative of the invention and is not intended to limit the same to the disclosed compounds and processes. Variations and changes which are obvious to one skilled in the art are intended to be within the scope and nature of the invention as defined in the claims.
