Participants

Reaction Steps

A sample of N-((S)-1-((3R,4S)-3-(isopropylsulfonylmethyl)piperidin-4-yl)-2-oxopyrrolidin-3-yl)-3-(trifluoromethyl)benzamide (0.05 g) was dissolved in 1,2-dichloroethane (3 mL) prior to the addition of acetone (0.38 mL, 0.525 mMol). After stirring at rt for 1 h, sodium triacetoxyborohydride (0.445 g, 0.21 mMol) was added to the reaction. Stirring was continued for 2 h when the reaction was quenched with saturated NaHCO3. Partitioned between EtOAc and water. Organic layer was washed with brine and dried (MgSO4). Filtered, concentrated and chromatographed. The desired product, N-((S)-1-((3R,4S)-1-isopropyl-3-(isopropylsulfonylmethyl)piperidin-4-yl)-2-oxopyrrolidin-3-yl)-3-(trifluoromethyl)benzamide (0.0086 g, yield=16%) was obtained as a white solid. MS found: (M+H)+=518.2
