4-Methyl-3-nitro-benzoic acid (71 g, 0.39 mol) was dissolved in dry EtOH (600 mL) and dry HCl gas was bubbled into the solution for 5 min. The reaction was heated to 90° C. under N2 for 20 h, then cooled and concentrated to give 4-methyl-3-nitro-benzoic acid ethyl ester as a straw-color liquid (80.0 g, yield 98%).
