Dihexylamine → 4-(N,N-di-n-hexylamino)-3-ethoxy-1,1-dioxo-1,2,5-thiadiazole

Participants

Reaction Steps

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 4-(N,N-di-n-hexylamino)-3-ethoxy-1,1-dioxo-1,2,5-thiadiazole (120 mg, 72%). MS (EI, m/e 345).
