反応手順
To a solution of 4-(methylsulfonyl)acetophenone (4.85 g, 24.5 mmol) in CHCl3 (70 ml) was added aluminum chloride (1 mg) and bromine (1.1 mL) in CHCl3 (8.5 mL) dropwise. The mixture was stirred overnight, and poured into water. The whole was extracted with ethyl acetate (50 mL×2), the combined organic layer was dried over MgSO4, and concentrated in vacuo. The resulting residue was recrystallized from ethyl acetate/hexane (1/1) to give the subtitle compound (5.28 g, 78% yield).
