Participants

Reaction Steps

20.3 parts of 1-phenyl-4-amino-6-chloropyridazinium perchlorate, 200 parts of water, 10parts of sodium bicarbonate and about 5 parts of Raney nickel are stirred for about three hours and in an autoclave at 20° to 25° C and a hydrogen pressure of 200 atmospheres gauge. The reaction solution is filtered from catalyst and evaporated. The crystalline residue is washed with a little water. 15.6 parts (86.7% of theory) of 1-phenyl-4-aminopyridazinium perchlorate is obtained; C10H10O4N3Cl, melting point 184° to 186° C after having been recrystallized from methanol.
