Procedure

A mixture of 3-allylthio-5-chloro-1,2,4-thiadiazole (15.0 g), thiourea (5.95 g), tetrahydrofuran (45 ml) and water (15 ml) was gently boiled for 8.5 hours at 65° C. The reaction mixture was post-treated according to conventional manner to give powder of 3-allylthio-1,2,4-thiadiazole-5-thiol (8.5 g), mp. 107° to 108° C.
