Procedure

61.8 g (0.3 mol) of 2-chloro-3a,4,5,6-tetrahydroperimidine are heated to 80° C. with 19.2 g (0.6 mol) of anhydrous hydrazine in 250 ml of ethanol for 4 hours. After cooling the mixture, 250 ml of petroleum ether are added and the crystals formed are isolated by filtration. 2-Hydrazino-3a,4,5,6-tetrahydro-perimidine is obtained. Yield: 54 g (89% of theory) of melting point 191°-193° C.
