Procedure

To a solution of 1-butanethiol (2.7 g, 30 mmol) and sodium hydride (1.2 g, 30 mmol) in dry tetrahydrofuran was added a solution of 3-(4-chloro-1,2,5-thiadiazol-3-yl)pyridine (1.2 g, 6 mmol) in dry tetrahydrofuran. The reaction mixture was stirred at -10° for 0.5 h. Water was added and the mixture was extracted with ether. The ether phase was dried and evaporated. The residue was purified by column chromatography (SiO2, eluent: ethyl acetate/methylene chloride (1:1)) to give the title compound.
