Procedure

A mixture of methyl thiosalicylate (7.4 g, 43.8 mmol), tert-butyl 3-[3-[2-cyano-4-pyridyl]propoxy]propanoate (14.0 g, 48.2 mmol), triethylamine (7.1 g, 70.2 mmol) and toluene (37 ml) was refluxed under nitrogen atmosphere for 24 hrs. The reaction mixture was concentrated under reduced pressure, subjected to a column chromatography and eluted with ethyl acetate-hexane (3:2, v/v) to give the titled compound (17.7 g, 86%).
