Procedure

Diethyl 2-(6-cyano-2-pyridyl)ethylphosphonate (0.80 g, 2.9 mmol) and methyl thiosalicylate (1.00 g, 5.9 mmol) were dissolved in toluene (4 ml), and triethylamine (2.0 ml, 14.3 mmol) was added thereto. The mixture was refluxed for 5 hrs. After cooling, the precipitated crystals were collected by filtration and recrystallized from diisopropyl ether-ethanol to give the titled compound (0.61 g, 50%) as white crystals.
