Methoxylation of 3,4,6-trichloropyridazine (1) with sodium methoxide was investigated in detail.Dimethoxylation of 1 afforded 6-chloro-3,4-dimethoxypyridazine (5) and a molecular complex (M) which is composed of 5 and 3-chloro-4,6-dimethoxypyridazine (6) in a ratio of 1:1.The nature of the complex (M) was examined by thermal and X-ray analyses.The molecular complex (M) was also obtained by monomethoxylation of 3,6-dichloro-4-methoxypyridazine (3) with sodium methoxide.
