Vorschrift

A solution of 6-methoxy-2-nitrobenzoic acid (3.25 g, 16.5 mM) in ethanol (180 mL) containing 10% palladium-on-carbon catalyst (0.30g) was hydrogenated using a Parr apparatus. When hydrogen consumption ceased, the resulting mixture was filtered through diatomaceous earth and the filtrate concentrated to provide the title benzoic acid (2.76 g, 100%) as a tan solid; MS(CI): 168 (M+H).
