実験手順

To a suspension of 0.804 gm (3.5 mMol) 5-amino-3-(1-methylpiperidin-4-yl)-1H-indole in 10 mL tetrahydrofuran and 5.0 mL dimethylformamide were added 0.536 mL (4.2 mMol) triethylamine followed by a solution of 0.714 gm (3.86 mMol) 2-chloro-4-fluorobenzoyl chloride in 5 mL tetrahydrofuran. After 18 hours the reaction mixture was diluted with ethyl acetate followed by 2N sodium hydroxide. The phases were separated and the aqueous extracted with ethyl acetate. The organic extracts were combined then washed sequentially with 2N sodium hydroxide, water and saturated aqueous sodium chloride. The remaining organics were dried over sodium sulfate and concentrated under reduced pressure. The residue was subjected to flash chromatography, eluting with 100:10:1 dichloromethane:methanol:ammonium hydroxide. Fractions shown to contain product were combined and concentrated under reduced pressure. The residue was precipitated from ethyl acetate to give 0.921 gm (68.2%) of the title compound as a light pink powder.
