Step B Preparation of 6-nitro-3,4-ethylenedioxybenzoic acid methyl ester To a solution of 5.0 g. of 3,4-ethylenedioxybenzoic acid methyl ester in 5.0 mls. of glacial acetic acid is added dropwise 5.0 mls. of 70percent nitric acid at 50¡ã-60¡ãC. After addition the reaction mixture is kept at 55¡ãC. for one hour, then cooled and 50 mls. of ice water added. The resulting precipitate is recovered by filtering, water washed and dried to obtain 6-nitro-3,4-ethylenedioxybenzoic acid methyl ester, m.p. 115¡ã-118¡ãC.

The synthetic route of 20197-75-5 has been constantly updated, and we look forward to future research findings.
