实验步骤: 0.93 g of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-5-vinyl-3-quinolinecarboxylic acid, 0.69 g of decahydropyrrolo[3,4-b]pyrrolizine and 0.36 g of DABCO are refluxed for 2 hours in a mixture of 6 ml of acetonitrile and 3 ml of dimethylformamide. At room temperature, the reaction mixture is treated with 20 ml of water, and the solid is filtered off with suction, washed with water and dried. 0.7 g. of 1-cyclopropyl-6,8-difluoro-1,4-dihydro-7-(octahydro-pyrrolo[3,4-b]pyrrolizin-2-yl)-4-oxo-5-vinyl-3-quinolinecarboxylic acid is obtained. the solid is filtered off with suction washed with water dried

实验步骤: 9 g (40 mmol) of ethyl 1,4-diazatricyclo[6.3.0.02,6 ]undecane-4-carboxylate together with 50 ml of concentrated hydrochloric acid are refluxed overnight. The mixture is rendered alkaline using potassium carbonate and extracted ten times using 50 ml portions of chloroform, the extracts are dried over potassium carbonate and concentrated, and the residue is distilled. extracted ten times the extracts are dried over potassium carbonate concentrated the residue is distilled
