실험 절차

A solution of iodine monochloride (8.2 g, 50.5 mmol) in dry diethyl ether (100 mL) was added drop-wise over 45 minutes to a cold solution (0° C.) of resorcinol (5.5 g, 49.9 mmol) in dry ether (50 mL). After stirring at room temperature for one hour 100 mL of water and 1.0 g of sodium sulfite was added. The organic phase was separated and the aqueous phase was washed with 100 mL of ether, the combine ether phase was dried over sodium sulfate and evaporated under reduced pressure. The residue was purified using flash chromatography over silica gel using a mixture of CH2Cl2:MeOH (100:1) to provide the title compound in 50% yield. 1HNMR (300 MHz, CDCl3) δ 4.95 (s, 1H), 6.23 (m, 1H), 6.55 (m, 1H), 7.43 (m, 1H). MS (CDI) m/z 237 (M+H)+.
