反应详情

A solution of 7,7-dimethyl-2-methylsulfanyl-5-oxo-5,6,7,8-tetrahydro-quinoline-3-carbonitrile (0.25 g, 1 mmol) and piperidine (0.32 ml, 4 mmol) in dry ethanol (3 ml) was stirred at reflux for 36 h. The reaction mixture was then evaporated under reduced pressure. The residue was purified by flash chromatography on silica gel (chloroform-methanol, 50:1) to give the title compound (0.08 g, 28%) as a colorless solid.
