Abstract
By using 3-chloro-6-methylpyridazine as the starting material,two new synthetic routes were realized for the preparation of 6-methoxypyridazine-3-carboxylic acid through methoxy reaction of chlorine and oxidation to carboxylic acid of methyl group in synthetic sequence changes.The overall yield of 6-methoxypyridazine-3-carboxylic acid obtained by these two routes was 28.7% and 37.7%,respectively.
