Reaction Steps
Methyl 3-(hydroxymethyl)-5-nitrobenzoate (11.2 g, 53 mmol) in methanol (50 mL) was flushed with nitrogen, and treated with palladium (10% on charcoal, 1.1 g). The flask was flushed with hydrogen and allowed to stir under an atmosphere of hydrogen overnight. The reaction was flushed with nitrogen, filtered through celite, and concentrated. Column chromatography on silica gel (50% ethyl acetate/hexanes) afforded 2.8 g (29%). 1H-NMR (CD3OD, 300 MHz) δ 7.34 (s, 1H), 7.27 (s, 1H), 6.94 (s, 1H), 4.55 (s, 2H), 3.88 (s, 3H). Mass spec.: 182.09 (MH)+.
