Reaction Steps

(S)-N-[[3-[4-[cis-3-(Carbobenzyloxy)-3,7-ciazabicyclo[3.3.0]octan-7-yl]-3-fluorophenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (150 mg, 0.30 mmol), methylene chloride (5 mL), and methanol (10 mL) are combined with 10% palladium on carbon (30 mg) and placed under a hydrogen atmosphere (balloon) for 15 hours. The reaction is filtered through celite and concentrated in vacuo to give crude (S)-N-[[3-[4-[cis-3,7-diazabicyclo[3.3.0]octan-7-yl]-3-fluorophenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide. The crude amine is taken up in methylene chloride (15 mL), cooled to 0° C., and triethylamine (0.09 mL, 0.67 mmol) and benzyloxyacetyl chloride (0.06 mL, 0.40 mmol) are added. The reaction is warmed to ambient temperature, stirred 15 hours, and diluted with methylene chloride (100 mL). The organic phase is washed with water (2×50 mL) and saline (150 mL), dried over sodium sulfate, concentrated in vacuo, and chromatographed on silica gel (230-400 mesh, 100 mL), eluting with chloroform/methanol (95/5). The appropriate fractions are combined (Rf =0.41, TLC, chloroform/methanol, 90/10) and concentrated in vacuo to give the title compound, mp 138-140° C.
