Dihexylamine (90 mg, 0.48 mmol) was added to a solution of 3,4-diethyloxy-1,1-dioxo-1,2,5-thiadiazole (100 mg, 0.48 mmol) in ethanol (5 mL) and the reaction stirred overnight at room temperature. The solvent was removed under reduced pressure and the residue absorbed onto silica gel; and purified by flash column chromatography (silica, hexane:EtOAc 3:1) to yield the title intermediate (120 mg, 72%).
