    From p-nitrotoluene, in sulfuric acid, using sodium dichromate oxidation, formation of p-nitrobenzoic acid, esterification with ethanol, after the completion of the reaction, separation, the ethyl p-nitrobenzoate in acetic acid solution, with iron powder in 85 ~ 95 DEG C reduction, available benzocain crude. After the separation, water washing, and then recrystallization in ethanol.
