Procedure

Ethyl 5-(6-cyano-2-pyridyl)valerate (0.34 g, 1.5 mmol) and methyl thiosalicylate (0.40 g, 2.4 mmol) were dissolved in toluene (2 ml), and triethylamine (0.43 ml, 3.1 mmol) was added thereto. The reaction mixture was refluxed for 14 hrs and subjected to a silica gel (25 g) column chromatography. The fractions eluted with hexane-ethyl acetate (3:1, v/v) were collected and concentrated. The residue was recrystallized from ethanol-hexane to give the titled compound (0.41 g, 76%) as white crystals.
