Methyl thiosalicylate (0.44 g, 2.6 mmol) and 2-(hexylamino)isonicotinonitrile (0.26 g, 1.3 mmol) were dissolved in toluene (2.0 ml), and triethylamine (0.40 ml, 2.9 mmol) was added thereto. The reaction mixture was refluxed for 14 hrs, subjected to a silica gel (50 g) chromatography, eluted with hexane-ethyl acetate (2:1, v/v) and recrystallized from ethanol to give the titled compound (0.08 g, 18%) as white crystals.
