A solution of 6-(4-pyridyl)-4H-benzo[1,4]oxazin-3-one (0.57 g, 2.52 mmol), in methanol (15 mL) was treated with platinum (IV) oxide (50 mg, 0.22 mmol) and 1M HCl in ether (2.7 mL) and stirred at room temperature under an atmosphere of hydrogen for 24 h. The reaction mixture was filtered through celite and the filtrate evaporated in vacuo to give the title compound (0.59 g, 87%) as a pale yellow solid.
