Procedure

A solution of Oxone™ (12 g, 0.0195 mol) in H2O (60 mL) was vigorous stirred as 3-chloro-4-butylthio-1,2,5-thiadiazole (2.1 g, 0.01 mol) in THF (30 mL) was added dropwise. After 24 h, the THF was evaporated and the residue extracted with ether (3×). Extracts were washed with H2O, dried, and solvent evaporated to give a clear liquid. Radial chromatography eluting with 30% EtOAc/hexane gave a colorless liquid (2.3 g). (Compound 2).
