Reaction Steps

To 3-hydroxy-4-nitrophenylacetic acid (5.45 g, 27.6 mol) and methanol (100 ml) was added concentrated sulfuric acid (0.5 ml). The mixture was then heated under reflux for 4 hours under stirring. After cooling to room temperature, the reaction mixture was distilled under reduced pressure to remove the solvent. Water (100 ml) was added to the residue, followed by extraction with ether (300 ml). The extract was washed successively with a saturated aqueous solution (100 ml) of sodium bicarbonate and saturated brine (100 ml), dried over anhydrous magnesium sulfate and distilled under reduced pressure to remove the solvent, whereby the title compound (4.90 g, 84%) was obtained as a yellow crystalline powder.
