Procedure

To a solution of sodium (230 mg, 10 mmol) in 1-pentanol(20 ml) was added 3-(3-chloro-1,2,5-thiadiazol-4-yl)pyridine (490 mg, 2.5 mmol). The mixture was stirred at 50° C. for 3 h and evaporated. The residue was dissolved in water and extracted with methylene chloride. The combined organic phases were dried and evaporated to give the wanted compound.
