Procedure

24 g of furfural and 26.5 g of thiocarbohydrazide in 150 ml of methanol are vigorously stirred. Stirring is continued for 30 minutes after the exothermic reaction has died down. The precipitate is suction filtered and recrystallised from methanol. 30.1 g of furfurylidene thiocarbohydrazide, melting at 186° to 187° C. are obtained.
