    • 4 (0.1 mmol) in anhydrous acetonitrile (6 mL) under an argon atmosphere at rt. The reaction mixture was refluxed until completion of the reaction (usually 4-8 h, monitoring by TLC). Most of the acetonitrile was removed in vacuo and the crude reaction mixture was partitioned between EtOAc and water. The organic layer was washed with water, brine and dried over anhydrous sodium sulfate. It was concentrated in vacuo to give a crude product, which was purified by silica gel column chromatography using EtOAc and hexane to give the pure vicinal aminosulfonamide.
