실험 절차

One prepared 4,4-dimethyl-1-ethyl-1,2,3,4-tetrahydro-2-oxo-7-quinolinecarboxylic acid analogously to the procedure for 4,4-dimethyl-1,2,3,4-tetrahydro-2-oxo-7-quinolinecarboxylic acid (DE-A-3,818,830) as follows: one stirred 4,4-dimethyl-1,2,3,4-tetrahydro-2-oxo-7-quinolinecarbonitrile (2.0 g, 10.0 mmol), iodoethane (1 ml, 12.0 mmol) and potassium carbonate (1.70 g, 12.0 mmol) for one hour at 60° C., again added iodoethane (2 ml, 24 mmol) and potassium carbonate (2.5 g, 25 mmol) thereto and stirred for one hour at 60° C. One allowed to cool to room temperature, stirred the solution into water, filtered off the precipitate with suction and dried in a vacuum. One obtains 4,4-dimethyl-1-ethyl-1,2,3,4-tetrahydro-2-oxo-7-quinolinecarbonitrile (1.1 g, 48%) with the m.p.=120°-121° C.
