실험 절차

Iodine (2.82 g; 11.10 mmol) was added to a stirred mixture of silver sulphate (3.46 g; 11.10 mmol) and 1-(4-aminophenyl)ethanone (1.50 g; 11.10 mmol) in ethanol (40 mL). The reaction mixture was then stirred at room temperature for 18 hours and filtered over celite. The volatiles were removed under reduced pressure and the residue was partitioned between ethyl acetate and a saturated aqueous solution of sodium thiosulfate. The organic layer was washed with brine, dried and concentrated under reduced pressure. The crude residue was purified by flash chromatography on silica gel (eluent 2 to 40% ethyl acetate in heptane) to afford 0.514 g (18%) of the title compound as a pale yellow solid.
