Procedure

tert-Butyl 3-(2-cyano-4-pyridyl)propionate (0.51 g, 2.2 mmol) and methyl thiosalicylate (0.55 g, 3.3 mmol) were dissolved in toluene (2 ml), and triethylamine (0.47 ml, 3.4 mmol) was added thereto. The mixture was refluxed for 8 hrs and subjected to a silica gel (30 g) column chromatography. The fractions eluted with hexane-ethyl acetate (3:1, v/v) were collected and concentrated to give the titled compound (0.56 g, 69%) as white crystals.
