Procedure

To a solution of the carboxylic acid (2.7 g, 11 mmol) from step A and tert-butyl (3S)-pyrrolidin-3-ylcarbamate (2.0 g, 11 mmol) in DMF (30 mL) cooled in an ice bath was added BOP (5 g, 11 mmol) followed by triethylamine (3 mL, 22 mmol). The mixture was allowed to warm to temperature and stirred overnight. Ethyl acetate (150 mL) was added. The resulting solution was washed with NaHCO3 and brine each three times, dried over MgSO4 and concentrated. Chromatography on silica gel eluting with EtOAc provided 4.4 g (96%) of the desired product. MS (M-Boc+H)+ 316.
