Abstract
This invention is directed to a process of preparing alkyl N-alkylanthranilate, specially Methyl N-methylanthranilate, represented by Formula (I), in a one pot synthesis, using available and cheap commercial chemicals such as Isatoic anhydride, solid sodium hydroxide, dimethyl sulfate and methanol. Purity of the crude product is about 97% and yield 85%.
