Reaction Steps

To a solution of (4-phenyl-1,2,5,6-tetrahydropyridin-3-yl)methanol hydrochloride (110 mg, 0.49 mmol) in DCM (2 mL) was added DIPEA (0.17 mL, 0.98 mmol) and Ac2O (0.05 g, 0.49 mmol), 15 min later, it was diluted with water and extracted with DCM. Organic layers were combined, dried and concentrated, the resulting crude oil was purified by column (EtOAc followed by DCM/MeOH=9:1) to give 1-(5-(hydroxymethyl)-4-phenyl-3,6-dihydropyridin-1(2H)-yl)ethan-1-one (88 mg).
