Reaction Steps

4′-Amino acetophenone (1.20 g, 5.29 mmol) was dissolved in THF (8 ml) before pyridine (1.28 ml, 15.8 mmol) was added, leaving a yellow solution. The naphthalenesulfonylchloride (0.715 g, 5.29 mmol) was then added dropwise with stirring. After stirring for 5 hours, THF and pyridine were removed in vacuo. The desired sulfonamide (1.074 g, 3.30 mmol, 62%) was recrystallized from ethyl acetate and hexanes. It had LC-MS (ES+): 326 [MH]+ m/e
