Procedure
4-Ethoxycarbonylmethyl-thiosemicarbazide (8.33 g) (GANTE and LANTSCH, Chem. Ber., 97, 989 (1964)) are suspended in a saturated solution (250 cc) of ammonia in ethanol, and the reaction mixture is stirred at 25° C. for 22 hours. The insoluble matter is filtered off and washed with alcohol (2×25 cc) and ether (2×50 cc); after drying, 4-carbamylmethyl-thiosemicarbazide (6.2 g), m.p.=188° C., is obtained.
