Procedure

tert-Butyl 3-(2-cyano-6-methyl-4-pyridyl)propanoate (1.2 g, 4.8 mmol) and methyl thiosalicylate (1.6 g, 9.9 mmol) were dissolved in toluene (10 ml), and triethylamine (4.0 ml, 28.6 mmol) was added thereto. The mixture was refluxed for 24 hrs. The solvent was evaporated, and the residue was subjected to a silica gel column chromatography. The fractions eluted with ethyl acetate-hexane (1:2, v/v) were collected, concentrated and recrystallized from tetrahydrofuran-hexane to give the titled compound (1.2 g, 66%).
