AbstractLipase‐catalyzed synthesis of esters of anthranilic acid was attempted by employing alcohols of carbon chainlength C1–C18 using Plackett‐Burman experimental design. Of the alcohols employed, methanol, decanol, cetyl alcohol, and stearyl alcohols showed 99.9% significance. Esterification of anthranilic acid with methanol gave the highest yield at 45.6%. This study allows the selection of better alcohols for esterification of anthranilic acid.
