Reaction Conditions

Reaction Steps

A mixture of 2-oxo-1-(3-trifluoromethyl-phenyl)-pyrrolidine-3-carboxylic acid ethyl ester obtained in step 2 (0.5 g, 1.6 mmol) and ethanol were cooled to 10-15° C. Sodium borohydride (0.126 g, 3.3 mmol) was added portion wise over a period of 20 min and the reaction mixture was stirred for 3.5 hrs at 20-25° C. The organic volatiles were evaporated and the residue was taken into brine solution (15 ml). The aqueous layer was extracted with ethyl acetate, dried over Na2SO4 and evaporated to obtain brown semi solid which was purified by preparative TLC to afford 3-Hydroxymethyl-1-(3-trifluoromethyl-phenyl)-pyrrolidin-2-one as a colorless oil (0.177 g, 43%).
