Reaction Steps

To a solution of (5)-tert-butyl 3-(2-chloro-3-fluorophenyl)-3-((R)-1,1-dimethylethylsulfinamido)butanoate (8.75 g, 22.33 mmol) in tetrahydrofuran (100 mL) was added lithium borohydride, 2.0M in THF (29.9 mL, 59.8 mmol) dropwise, followed by MeOH (7.05 mL, 174 mmol). The reaction was stirred for 40 min and was carefully quenched by the addition of saturated ammonium chloride (75 mL), followed by water (100 mL) and EtOAc. The separated organic phase was washed with brine, dried over sodium sulfate and filtered to give (R)-N-((S)-2-(2-chloro-3-fluorophenyl)-4-hydroxybutan-2-yl)-2-methylpropane-2-sulfinamide as a white solid (7.2 g, 100% yield). MS m/z=322 [M+H]+. Calculated for C14H21ClFNO2S: 321.8.
