Reaction Steps

To a solution of sodium (440 mg, 17 mmol) in ethanol (10 ml) was added 3-(4-chloro-1,2,5-thiadiazol-3-yl)pyridine (540 mg, 3.3 mmol). The mixture was stirred at 40° C. for 10 h and evaporated. The residue was dissolved in water and extracted with methylene chloride. The combined organic phases were dried and evaporated to yield 520 mg (76%) of the title compound.
