Procedure

Benzyl mercaptan (0.99 g, 7.94 mmol) and sodium hydride (60% in oil, 0.35 g, 8.66 mmol) were added to THF (30 ml), and the mixture was stirred at room temperature for 1 hr. A solution of 2-chloro-6-cyanopyridine (1.00 g, 7.22 mmol) in THF (10 ml) was added dropwise to the reaction mixture, and the mixture was stirred at room temperature for 18 hrs. The reaction mixture was combined with ethyl acetate and brine. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated to give the titled compound (1.63 g, 100%) as a pale pink oil.
