Reaction Steps

Into a 100-mL round-bottom flask, was placed N-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-ethyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (400 mg, 0.68 mmol, 1.00 equiv), triphenylphosphine (400 mg, 2.20 equiv), THF (10 mL) and water (1 mL) and the reaction was stirred overnight at room temperature. The resulting mixture was concentrated under vacuum and applied onto a preparative thin-layer chromatography (TLC) plate, eluting with DCM:methanol (5:1). This resulted in 350 mg (73%) of N-(2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-ethyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide as yellow oil.
