Procedure

A mixture of methyl thiosalicylate (1.1 g, 6.4 mmol), 6-cyano-2-pyridinecarboxamide (0.47 g, 3.1 mmol), triethylamine (1.0 ml, 7.1 mmol) and toluene (3 ml) was refluxed for 6 hrs as described in Example. After cooling, the precipitated crystals were collected by filtration and recrystallized from hexane-ethanol to give the titled compound (0.63 g, 70%).
