실험 절차

A mixture of methyl thiosalicylate (0.43 g, 2.5 mmol), 2-cyano-5,6,7,8-tetrahydroquinoline (0.40 g, 2.5 mmol), triethylamine (0.50 ml, 3.8 mmol) and toluene (2.0 ml) was refluxed for 17 hrs. After cooling, the precipitated crystals were collected by filtration and recrystallized from ethanol to give the titled compound (0.22 g, 30%)
