실험 절차

A mixture of 0.5 g (1.8 mmole) 1-ethyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid, 5 ml acetonitrile, 0.27 g (1.8 mole) of 1,8-diazobicyclo[5.4.0]undec-7-ene, and 0.3 g (1.9 mmole) of N,N-diethyl-3-pyrrolidinemethanamine was stirred at room temperature overnight. The formed precipitate was filtered, washed with acetonitrile then ethyl ether until dry to yield 0.45 g (60%) of the title compound, mp 210°-211° C.
