実験手順

An autoclave containing a mixture of 3 g of 9-fluoro-8-chloro-5-methyl-6,7-dihydro-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid, 8 g of morpholine and 30 ml of hexamethylphosphoric triamide was immersed in an oil bath at 190° C. and reaction was continued for 5 hours. After completion of reaction, the reaction mixture was cooled to precipitate crystals which then were collected by filtration. The crystals thus obtained were recrystallized from dimethylformamide to give 0.77 g of 9-morpholino-8-chloro-5-methyl-6,7-dihydro-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid. m.p. 271° to 274° C., white rhombic crystals.
