Sulfamethoxypyridazine, N1
-(6-methoxy-3-pyridazinyl)sulfanilamide (33.1.43), is synthesized by replacing the chlorine atom in 6-chloro-3-(4-aminobenzenesulfonilamido)pyridazine with a methoxy group in 33.1.42 using sodium methoxide. The
initial 6-chloro-3-(4-aminobenzenesulfonylamido)-pyridazine (33.1.42) is in turn synthesized
by reacting 4-aminobenzenesulfanilamide with easily accessible 3,6-dichloropyridazine.
