Reaction Steps

12.2 parts of 1-methyl-4-amino-6-chloropyridazinium perchlorate in 150 parts of acetonitrile is stirred with 5 parts of phenol and 4 parts of pyridine for 4 hours at 80° C. The reaction mixture is filtered and the filtrate is concentrated at subatmospheric pressure. About 200 parts of water is added. 5.5 parts (36.6% of theory) of 1-methyl-4-amino-6-phenoxypyridazinium perchlorate is obtained; C11H12O5N3Cl, melting point 182° to 184° C after having been recrystallized from water.
