5-Methoxy-2-nitrobenzoic acid (4) (1.0 g, 5.1 mmol) was treated as described for the preparation of compound 3 to give 5-methoxy-2-nitrobenzamide (8). The intermediate was then dissolved in MeOH and hydrogenated over 10% Pd/C for 6 h. The catalyst was removed by filtration, and the solution was evaporated to afford 10 (0.8 g) as brown powder; MS m/z 166 (M+).
