摘要: 3-Methylpyridazine 1-oxide (II) and 2-oxide (III) were separated from the N-oxidation products of 3-methylpyridazine (I). Nitration II could not be accomplished, but III gave 3-methyl-mononitropyridazine (VI) in good yield. The nitro group VI was proved to 5-position. Reaction 3-methyl-6-methoxypyridazine (IX) with phosphoryl chloride 3-methyl-5-chloro-6-methoxypyridazine (XIX) acetic anhydride 6-methoxy-3-pyridazinemethanol acetate (XXI).
