Reaction Steps

Triphenylphosphine (3.9 g, 15 mmol) was added to a solution of sulfonamide 1-6 (4.5 g, 10 mmol) in THF (30 mL). To this solution was added a solution of diethyl azodicarboxylate (2.4 mL, 15 mmol) in THF/MeOH (10 mL/2.02 mL). A vigorous exotherm occurred and the reaction was stirred overnight at room temperature. The dark mixture was concentrated. The dark oily residue was purified by flash chromatography (40% EtOAc/hexanes) to give the desired product 1-7.
