Benzoyl chloride → 1-benzoyl-N,N-dimethylpyrrolidine-2-carboxamide

Participants

Reaction Steps

N,N-Dimethyl-L-prolinamide (2.50 g, 17.58 mmol) was dissolved in a mixture of CH2Cl2 (50 mL) and water (50 mL), then solid sodium bicarbonate (2.95 g, 35.16 mmol) was added, followed by benzoyl chloride (2.1 mL, 18.45 mmol). After stirring overnight, the phases were separated, and the aqueous phase was extracted with CH2Cl2 (3×50 mL). The combined organic phase was dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to provide N,N-dimethyl-1-(phenylcarbonyl)-L-prolinamide (4.502 g, >99%). LCMS: (M+H)+: 247.2.
