실험 절차

To a suspension of 14.73 g of 2-amino-5-thiazoleethanol, monohydrochloride (Example B) in 200 ml of chloroform is added rapidly 50 ml of thionyl chloride. The mixture is refluxed for 30 minutes, cooled to room temperature, filtered through a pad of Celite, concentrated to a brown oily solid, and crystallized from ethanol-diethyl ether to give 5-(2-chloroethyl)-2-thiazolamine as the monohydrochloride salt; mp 145°-147° C.
