실험 절차

A solution of 6-chloro-1-cyclopropyl-carbonyl-4-oxo-1,2,3,4-tetrahydroquinoline (1.996 g), N,N-dimethylformamide dimethyl acetal (3.808 g), and triethylamine (1.212 g) in benzene (16 ml) was refluxed with stirring for 30 minutes and then about three-fourths of the solvent was distilled slowly at atmospheric pressure over a period of approximately 30 minutes. To the residue was added benzene (16 ml) and the solvent was distilled again. The residue was dissolved in ethyl acetate, treated with activated charcoal, and evaporated in vacuo. The residual solid was washed with diethyl ether to give 6-chloro-1-cyclopropyl-carbonyl-3-dimethylaminomethylene-4-oxo-1,2,3,4-tetrahydroquinoline (2.43 g).
