Reaction Steps

0.93 g of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-5-vinyl-3-quinolinecarboxylic acid, 0.62 g of 4-amino-1,3,3a,4,7,7a-hexahydro-isoindole and 0.34 g of DABCO are refluxed for 1 hour in a mixture of 6 ml of acetonitrile and 3 ml of dimethylformamide. The reaction mixture is treated with 20 ml of water, and the product is filtered off with suction, washed with water and dried. 1 g of 7-(4-amino-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.
