Procedure

0.46 g of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-5-vinyl-3-quinolinecarboxylic acid, 0.34 g of 4-methylamino-1,3,3a,4,7,7a-hexahydro-isoindole and 0.18 g of DABCO are refluxed for 2 hours in a mixture of 3 ml of acetonitrile and 1.5 ml of dimethylformamide. At room temperature, the reaction mixture is treated with 20 ml of water, and the product is filtered off with suction, washed with water and dried. 0.5 g of 7-(4-methylamino-1,3,3a,4,7,7a-hexahydro-isoindol-2-yl)-1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-oxo-5-vinyl-3-quinolinecarboxylic acid is obtained.
