Procedure

tert-Butyl 3-(2,6-dicyano-3-pyridyl)propanoate (0.31 g, 1.20 mmol) and methyl thiosalicylate (0.40 g, 2.40 mmol) were dissolved in toluene (30 ml), and triethylamine (0.75 ml, 5.41 mmol) was added thereto. The mixture was refluxed for 18 hrs, and the solvent was evaporated. The residue was washed with hexane-ethyl acetate to give the titled compound (0.12 g, 25%) as white amorphous solid.
