Reaction Steps

Stir 1-(4-chloro-pyridin-2-yl)-piperazine hydrochloride (2.2 mmol, 0.4 g), triethylamine (7.6 mmol, 1.1 mL) in 13 mL of CH2Cl2 and pivaloyl chloride (2.2 mmol, 0.3 mL) overnight at room temperature. Add CH2Cl2 and wash with saturated aq. sodium chloride and water. Dry over sodium sulfate, filter, and concentrate under reduced pressure to give 1-[4-(4-chloro-pyridin-2-yl)-piperazin-1-yl]-2,2-dimethyl-propan-1-one. MS(ES): m/z=282 [M+H].
