Dimethylamine → (S)-5-chloro-6-(4-(3-(2-fluoro-4-(methylsulfonyl)phenylamino)-2-oxopyrrolidin-1-yl)piperidin-1-yl)-N,N-dimethylnicotinamide

Participants

Reaction Steps

To a solution of (S)-5-chloro-6-(4-(3-(2-fluoro-4-(methylsulfonyl)phenylamino)-2-oxopyrrolidin-1-yl)piperidin-1-yl)nicotinoyl chloride (0.15 g, 0.28 mmol) in 5 mL of DMF/ACN/THF (1:1:1) was added dimethylamine (2 M solution in THF, 1.4 mL, 2.8 mmol) and the reaction was stirred at ambient temperature for 4 hours. The reaction was diluted with EtOAc (100 mL) and the organic layer was washed with water (20 mL) and brine (20 mL), and the organic layer was dried over MgSO4, and concentrated under vacuum. The material was triturated with isopropanol (about 6 mL) to give (S)-5-chloro-6-(4-(3-(2-fluoro-4-(methylsulfonyl)phenylamino)-2-oxopyrrolidin-1-yl)piperidin-1-yl)-N,N-dimethylnicotinamide (0.059 g, 0.11 mmol, 38% yield). Mass spectrum (apci) m/z=538.0 (M+H).
