Reaction Steps

15 parts of 1-methyl-3-phenyl-4-methylamino-6-chloropyridazinium perchlorate, 100 parts of water, 5 parts of triethylamine and about 2 parts of Raney nickel are treated at room temperature in a shaking apparatus with hydrogen at atmospheric pressure. After twenty-four hours the reaction mixture is suction filtered, the residue is boiled with 200 parts of methanol and filtered and the filtrate is concentrated and cooled. 10.3 parts (76.6% of theory) of 1-methyl-3-phenyl-4-methylaminopyridazinium perchlorate is obtained; C12H14O4N3Cl, melting point 155° to 157° C.
