실험 절차

To a solution of 7-fluoro-1,3,3-trimethyl-6-(trimethylsilyl)indolin-2-one (9.9 g, 37.3 mmol) in dichloromethane (500 ml) at 0° C. was added iodine monochloride (37.3 ml, 37.3 mmol). The reaction mixture was warmed to room temperature and stirred for 16 hours. A saturated aqueous solution of sodium thiosulfate was added to the reaction mixture and the aqueous phase was extracted with dichloromethane. The combined organic layers were dried over sodium sulfate. The solvent was evaporated and the residue purified by silica gel chromatography using ethyl acetate/heptane as eluent. The title compound was obtained as off-white crystals (9.82 g).
