Reaction Steps

To a stirred solution of (S)-tert-butyl 1-(4-bromophenyl)ethyl(3-(4-fluorophenyl)-3-oxopropyl)carbamate (500 mg, 1.11 mmol) in MeOH (20 mL) was added an NaBH4 caplet (1 g, 26 mmol). The mixture was stirred at rt overnight and concentrated under reduced pressure. The residue was partitioned between EtOAc (80 mL) and water (20 mL). The organic layer was washed with brine, dried over Na2SO4 and concentrated to leave tert-butyl (S)-1-(4-bromophenyl)ethyl(3-(4-fluorophenyl)-3-hydroxypropyl)carbamate (474 mg, 94%) as an oil. LC-MS (3 min) tR=2.33 min, 454. 452, 380, 378.
