Reaction Steps
Commercially available 2-amino-4,5-dimethoxy-benzoic acid methyl ester (3 g, 0.014 mol) and acetic anhydride (4.03 mL, 0.0426 mol) were heated in heptane at 100° C. for 3 hours. After removal of heptane in vaccuo, the crude product of 2-acetylamino-4,5-dimethoxy-benzoic acid methyl ester was obtained and used without further purification. LC/MS: m/z 254 (M+H).
