Versuchsvorschrift
A stirred mixture of 1-chloro-3-(dimethylamino) propane hydrochloride (305.7 g), thiourea (150 g) and ethanol (1530 ml) was heated under reflux for 24 hours then cooled to ambient temperature. Ethyl acetate was added until a faint opalescence was observed, then the mixture was stored at 4° C. for 72 hours. The resulting solid was collected by filtration, washed with ethyl acetate, and dried in vacuo at 40° C. to give S-[3-(dimethylamino)propyl]isothiourea dihydrochloride as a white solid (403 g), m.p. 155°-157° C.
