A mixture of 5-methylthio-2-nitrobenzoic acid (25.4 g; 0.119 mole), methanol (200 ml) and Raney nickel (2 g) is shaken in an atmosphere of hydrogen at 50 lb pressure when theoretical amount of hydrogen is absorbed. The catalyst is filtered off and the filtrate evaporated to dryness. The residue is recrystallized from etheriso-Pr2O. Yield 7.6 g; mp 145°-150°.
