Participants

Reaction Conditions

Reaction Steps

A mixture of 1-(4-isopropyl-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid ethyl ester obtained in step 2 (0.7 g, 2.65 mmol) and ethanol were cooled to 10-15° C. Sodium borohydride (0.25 g, 6.6 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 4-hydroxymethyl-1-(4-isopropyl-phenyl)-pyrrolidin-2-one as an off white solid (0.5 g, 81%).
