To a stirred suspension of LAH (16 g, 90 mmol) in dry THF (200 mL) was added a solution of 3-(3-chlorophenyl)-3-oxopropanenitrile (10.4 g, 270 mmol) in dry THF (200 mL) dropwise at 0° C. under nitrogen atmosphere. The mixture was warmed to 25° C. and then heated at 60° C. for 3 hours. After cooling to 0° C., a saturated solution of sodium hydroxide was added dropwise and extracted with ethyl acetate (200 mL). The solution was dried over anhydrous sodium sulfate and concentrated to dryness. The crude 3-amino-1-(3-chloro-phenyl)-propan-1-ol obtained was used in the next step without further purification. (Yield 14.5 g, crude).
