실험 절차
To a solution of 7-fluoro-2H-3,1-benzoxazine-2,4(1H)-dione (5.01 g, 27.7 mmol) in DMF (100 ml) at 0° C. was added sodium hydride (1.11 g, 27.7 mmol, 60% in paraffin) over 15 min. Allyl iodide (2.6 ml, 27.7 mmol) was added and the solution stirred for 2 h, then poured onto ice (100 g) in water (200 ml). The precipitate was collected, washed with water, then hexane and dried under vacuum at 40° C. to yield the title compound (4.53 g, 74%) as an off-white solid.
