Procedure

To a solution of 3,5-dichloroisonicotinonitrile (346 mg, 2 mmol) in N,N-dimethylformamide (2 mL) was added sodium thiomethoxide (141 mg, 2 mmol) at 0° C. The mixture was stirred at room temperature for 4 hours. After completion of the reaction, the solution was concentrated under reduced pressure. To the resulting residue was added saturated aqueous sodium hydrogen carbonate and the mixture was extracted with ethyl acetate. The combined organic layer was separated, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/1) to give the desired product (92 mg, 25% yield).
