Procedure

2-[7-Fluoro-2H-1,4-benzoxazine-3(4H)-on-6-yl]-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (1.0 g) was stirred in acetic acid (20 ml) and fuming nitric acid (8 ml) was slowly added. Solution was stirred at ambient temperature for 1 hr and the clear solution was added to ice-water. Light yellow precipitate was separated by filtration to afford the title compound (0.95 g).
