Procedure

4-(1,2,3-triazol-1-yl)piperidine hydrochloride (100 mg) and DBU (80 mg) were added to a suspension of (-)-9,10-difluoro-3(S)-methyl-7-oxo-2,3-dihydro-7H-pyrido [1,2,3-de]-1,4-benzoxazine-6-carboxylic acid in acetonitrile (5 ml). The reaction mixture was refluxed for 48 hrs followed by stirring at room temperature for an additional 48 hrs. The reaction mixture was concentrated and the residue was diluted with water. The separated solid was filtered, washed with water and dried to yield 30 mg of desired product. m.p. 254°-255° C.
