1,2-Hydrazinedicarboxamide → HCID 20472824, compound

Participants

Reaction Steps

131 g of 3-butoxy propylamine and 120 g of hydrazodicarbonamide are stirred in 300 ml of N-methyl pyrrolidone for 1 hour at 150° C., for 2 hours at 175° C. and for 6 hours at 200° C. A deposit is precipitated on cooling which is isolated by filtration under suction and recrystallised from cyclohexane, giving 152 g (75% of the theoretical yield) of 4-(3-butoxypropyl)-1,2,4-triazolidine-3,5-dione in the form of colourless crystals melting at 83° to 85° C.
