摘要
It was found that chlorosulfonation of 3-methoxybenzoic acid leads to selective introduction of sulfo group in ortho position with respect to carboxylic group. The ortho-sulfochloride of methyl ester of 3-methoxy benzoic acid was obtained with the subsequent sulfo chlorination of methyl ester of 3-methoxy benzoic acid. This ester is a convenient product for synthesis of 5-methoxy-1,2-benzothiazole-3(2N)-one-1,1-dioxide.
