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