Sodium hydride → 2-(2-Furanyl)-1-(4-fluorobenzyl)-5-methanesulfonylindole

참여 물질

반응 단계

To a solution of the compound obtained in Example 8 (6) (150 mg) in N,N-dimethylformamide (6 ml), 60% sodium hydride (34.4 mg) was added at 0° C. under nitrogen atmosphere, and the mixture was stirred for 15 minutes. To the mixture was added 4-fluorobenzyl bromide (160 mg), followed by stirring for 2 hours. After completion of the reaction, the reaction solution was poured into a saturated aqueous ammonium chloride solution, extracted with toluene, washed with a saturated aqueous NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel column chromatography (methanol:chloroform=1:100) and silica gel preparative thin-layer chromatography (methanol:chloroform=1:100) to obtain 130 mg of the desired product as a pale brown oil.
