A mixture of 1,2-diaminobenzene (6.59 g), methyl 4-formylbenzoate (10.0 g) and sodium bisulfite (6.60 g) in methanol (500 mL) is stirred at reflux for 6 hours. The mixture is filtered and the solvent evaporated to leave a yellow solid. This solid is recrystallized from ethyl acetate/ethanol to give 2.92 g of the title compound as an oil-white solid.
