Procedure

Sodium hydrogen sulfide (220 mg, 3 mmol) was added over 30 min. to a solution of 3-(3-chloro-1,2,5-thiadiazol-4-yl)pyridine (0.59 g, 3 mmol) inDMF (20 ml) at room temperature. Potassium carbonate (1.24 g, 9 mmol) and iodopropan (0.76 g, 4.5 mmol) were added. The reaction mixture was stirredat room temperature for 30 min. Water was added and the mixture extracted with ether. The combined ether phases were dried and evaporated to give the title compound in 89% (0.63 g) yield.
