反応手順
A mixture of methyl thiosalicylate (1.01 g, 6.0 mmol), 2-furonitrile (0.57 g, 6.0 mmol), triethylamine (1.5 ml, 10.7 mmol) and toluene (20 ml) was refluxed for 24 hrs. After cooling, the precipitated crystals were collected by filtration and recrystallized from hexane-ethanol to give the titled compound (0.26 g, 19%).
