実験手順
Into a solution prepared by dissolving 0.63 g of 3-(4-fluorophenyl)-1-isopropyl-1H-indole in 3 mL of dichloromethane was added dropwise 0.77 g of phosphorus oxychloride at an inner temperature of 0 to 10° C., then, 0.92 g of trans-3-methoxyacrylonitrile was added dropwise. Then, the mixture was stirred overnight at room temperature to cause a reaction, further, the mixture was reacted for 6 hours at the reflux temperature. After completion of the reaction, the reaction liquid was added into 100 mL of 5 wt % aqueous sodium hydrogen carbonate, and extracted with ethyl acetate three times. The resulting organic layers were combined and washed with water, then, dried with anhydrous magnesium sulfate. The magnesium sulfate was filtrated off, and the resulting filtrate was concentrated to obtain a concentrated residue containing 3-[3-(4-fluorophenyl)-1-isopropyl-1H-indol-2-yl]acrylonitrile (trans-cis isomer mixture containing mainly trans isomer). The resulting concentrated residue was purified by silica gel column chromatography (developing liquid: n-heptane/ethyl acetate: 10/1 to 5/1) to obtain 0.34 g of trans-3-[3-(4-fluorophenyl)-1-isopropyl-1H-indol-2-yl]acrylonitrile (yellow solid). Yield: 45%
