Thionyl chloride (0.96 ml) was added dropwise to a solution of (E)-4-morpholino-2-buten-1-ol (1.03 g) in dichloromethane (10 ml) at ice-bath temperature. After 3 hours, the reaction mixture was evaporated under reduced pressure and the resulting residue was triturated with ethyl acetate to give (E)-4-morpholino-2-butenyl chloride hydrochloride (0.98 g).
