Participants

Reaction Steps

59.1 g of 3-chloro-5,6,7,8,9,10-hexahydrocycloocta[c]pyridazine and 25.2 g of thiourea are heated at reflux in 250 cc of absolute ethanol while stirring for 20 hours. The reaction mixture is subsequently concentrated and divided between chloroform and water. After concentrating the chloroform phase, crude 3-mercapto-5,6,7,8,9,10-hexahydrocycloocta[c]pyridazine is obtained and is recrystallized from 250 cc of absolute ethanol with the addition of carbon. M.P. 167°-170° (decomp.).
