Reaction Steps
3,4-Dihydro-2-methyl-3-oxo-1,4(2H)-benzoxazine (11.4 g) and succinic anhydride (7 g) were added to 93 g of aluminum chloride and 15.3 ml of dimethylformamide. The mixture was stirred at 70° C. for 2.5 hours and then poured onto ice, giving a solid which was collected by filtration and washed with water. Drying under vacuum gave 16.5 g of the title compound (90% yield), mp 198°-200° C.
