Procedure

2-Chloro-4-cyanopyridine (0.40 g, 2.9 mmol) was dissolved in tetrahydrofuran (1 ml), and 12% lithium methylate in methanol (1.0 g, 3.2 mmol) was added thereto. The reaction mixture was refluxed for 6 hrs, combined with water, extracted with ethyl acetate, washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give a mixture (0.30 g) containing 2-methoxyisonicotinonitrile. This mixture and methyl thiosalicylate (1.0 g, 5.9 mmol) were dissolved in toluene (3.0 ml), and triethylamine (1.0 ml, 7.2 mmol) was added thereto. The reaction mixture was refluxed for 8 hrs, subjected to a silica gel (60 g) column chromatography, eluted with hexane-ethyl acetate (2:1, v/v) to give the titled compound (0.05 g, 8%) as white crystals.
