Методика

Methyl 2-methyl-3-nitrobenzoate (10.0 g) is dissolved in acetic acid (50 ml) and thereto 5% Pd-C (1 g) is added to carry out catalytic reduction at room temperature under 1 atm. After 1.5 hours, the catalyst is filtered off. The reaction mixture is concentrated, and thereto is added water, and the mixture is made alkaline with potassium carbonate, followed by extraction with dichloromethane. The solvent is concentrated to give methyl 2-methyl-3-aminobenzoate (8.6 g).
