Procedure

A mixture of methyl thiosalicylate (2.0 g, 11.9 mmol), ethyl 6-cyano-2-pyridinecarboxylate (2.1 g, 11.9 mmol), triethylamine (3.0 ml, 21.5 mmol) and toluene (6 ml) was refluxed for 12 hrs as described in Example 1. The precipitated crystals were collected by filtration and recrystallized from diisopropylether-tetrahydrofuran to give the titled compound (3.0 g, 80%).
