실험 절차

To a solution of 16 g of AlCl3 dissolved in 21.6 g of anisol was added dropwise 17.6 g of benzenesulfonyl chloride. The reaction mixture was heated to reflux for 8 hours and poured into 1N HCl solution containing ice. The resultant solution was extracted with ethyl acetate (100 ml×3), washed with 100 ml of saturated NaHCO3 aqueous solution, dried over Na2SO4 and concentrated to obtain residue, which was recrystallized from hexane-ethyl acetate to obtain 25 g of the title compound.
