Participants

Reaction Steps

1.5 g of 3-hydrazino-5,6,7,8,9,10,11,12,13,14-decahydrocyclododeca[c]pyridazine fumarate are heated in 20 cc of acetone, to which a few drops of concentrated aqueous ammonia solution have been added, on a water bath for 1 hour. The mixture is cooled with ice, and the resulting crude title compound is divided between 5 cc of concentrated aqueous caustic soda solution and 20 cc of chloroform. The chloroform phase is concentrated, whereby a yellowish foam results, from which the title compound is obtained by recrystallization from absolute ethanol. M.P. 165°-166° (decomp.).
