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 24 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.
