Reaction Steps

422 mg of 9,10-difluoro-2,3-dihydro-3methyl-7-oxo-7H-pyrido[1,2,3-de][1,4]-benzoxazine-6-carboxylic acid, 490 mg of 5-acetamidomethylisoindoline hydrobromide, 795 mg of DBU, and 3 ml of anhydrous DMF were processed in the same manner as in Example 20 to produce 382 mg of 10-(5-acetamidomethyl-2-isoindolinyl)-9-fluoro-2,3-dihydro-3-methyl-7-oxo-7H-pyrido[1,2,3-de][1,4]-benzoxazine-6-carboxylic acid.
