To a solution N-(2-acetyl-6-nitro-phenyl)-acetamide (0.3 g, 13.5 mmol) in ethanol (5 mL), was added an aq. solution of 5 N HCl (4.5 mL) and the reaction mixture was heated to reflux for one hour. After completion of the reaction, the reaction mixture was cooled to room temperature and evaporated under reduced pressure. The residue was diluted with water (25 mL) and extracted with ethyl acetate (2×25 mL). The combined organic layers were washed with a 10% aq. solution of sodium bicarbonate followed by water and dried over anhydrous sodium sulphate, then concentrated to dryness and purified by column chromatography using 15% ethyl acetate in hexane to get the title compound as yellow solid (0.20 g, 82.30%)
