Procedure

2-Methyl-6-nitrobenzoic acid is reacted with trimethylsilyldiazomethane to yield methyl 2-methyl-6-nitrobenzoate with m.p. 44–45° (Chem. Pharm. Bull., Vol. 29, 1475 (1981)). Methyl 2-methyl-6-nitrobenzoate is hydrogenated in methanol in the presence of palladium, 10% on carbon powder, at room temperature and atmospheric pressure to give methyl 2-methyl-6-aminobenzoate.
