Versuchsvorschrift

A solution of 4-trifluoromethyl-6-iodo-1H-indole-2,3-dione (12.0 g, 35.2 mmol) in N,N-dimethylformamide (120 mL) was cooled to 0° C. under nitrogen, and thereto was added 55% sodium hydride (1.70 g, 39.0 mmol) and the mixture was stirred for 30 minutes. Then, to the reaction solution was added dropwise 2-(trimethylsilyl)-ethoxymethyl chloride (7.00 mL, 39.6 mmol), and the mixture was stirred at room temperature for 5 minutes. To the reaction solution was added water, and the mixture was extracted with ethyl acetate-toluene (1:1) twice, washed with water twice, and then dried over magnesium sulfate, and filtered. The filtrate was evaporated and purified by silica gel column chromatography (hexane/ethyl acetate=5/1) to give the titled compound (13.7 g, 83%).
