Abstract
2-(7-Fluoro-3-oxo-3,4-2H-benzo-[b][1,4]oxazin-6-yl)-isoindoline-1,3-diones were synthesized by the reaction of 6-amino-7-fluoro-2H-benzo[b][1,4]oxazin-3(4H)-one with isobenzofuran-1,3-dione inacetic acid using amino resin a as scavenger reagent. The purities were 86%~95% and the structures were characterized by ~1H NMR, IR and MS.
