Hexane → 3-Dimethylamino-1-(2-chloro4-pyridyl)-2-propen-1-one

Participants

Reaction Steps

A mixture of 4-acetyl-2-chloro-pyridine (1.72 g, 11 mmol) in N,N-dimethyl formamide diethyl acetal (10 mL) is heated to reflux for 1 hour and cooled to room temperature before adding hexane (8 mL). The solid is collected by filtration, washed with hexane and dried to give 3-dimethylamino-1-(2-chloro-4-pyridyl)-2-propen-1-one (1.70 g); ESI-MS (m/z): 211.0 (M++H).
