42.0 Grams (0.338 mole) of benzyl mercaptan were dissolved in 350 ml dimethylformamide which had been dried over molecular sieves. The solution was placed under a nitrogen atmosphere and 16.2 grams (0.338 mole) of a 50 percent dispersion of sodium hydride was slowly added. Stirring was continued until hydrogen gas evolution stopped. Thereupon, the resulting solution was added slowly, again with stirring, to a solution of 50.0 grams (0.338 mole) of 2,3-dichloropyridine in 200 ml dry dimethylformamide. The mixture was heated at 70° C. for 4 hours.
