YieldReaction ConditionsOperation in experiment
87% With triethylamine; In acetonitrile; at 20 - 70℃; (4-Methoxyphenyl)(piperidin-4-yl)methanone hydrochloride (524 mg, 2.05 mmol) was stirred at room temperature with triethylamine (0.657 mL, 477 mg, 4.71 mmol) in acetonitrile (80 mL). A solution of ethyl 2-(3-bromo-2-oxopyrrolidin-1-yl)acetate (513 mg, 2.05 mmol) in acetonitrile (20 mL) was added to the mix. The reaction was stirred 3 hours at 40C and then overnight at 50C. After 24 hours the reaction was not complete and the reaction was stirred an additional 48 hours at 70C then allowed to cool to room temperature. The solvents were removed in vacuo. The crude orange solid was eluted through a silica gel column with a 0 to 10% methanol / dichloromethane gradient to afford the title racemic compound (730 mg, 87% yield, 95% purity) as a thick amber oil.
