実験手順

A mixture of 3.37 g of 8-methanesulfonyloxy-6,7-dihydro-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid, 9.1 g of 1-trifluoromethylpiperazine and 200 ml of anhydrous dimethyl sulfoxide was heated with stirring in an autoclave at 170° to 180° C. for 20 hours under nitrogen gas flow at a pressure of 8 atms. The reaction mixture was treated in the same manner as in Example 73 and further treated with concentrated hydrochloric acid to obtain 1.7 g of 8-(4-trifluoromethyl-1-piperazinyl)-6,7-dihydro-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid hydrochloride as white rhombic crystals having a melting point of 300° C. or more.
