الإجراء التجريبي
5-Aminoindole (100 mg, 0.757 mmol) was dissolved in DMF (2 mL), and the solution was added with EDCI (290 mg, 1.51 mmol), HOBT monohydrate (102 mg, 0.755 mmol) and 1-(tert-butoxycarbonyl)piperidine-4-carboxylic acid (208 mg, 0.907 mmol), followed by stirring at room temperature for 2 hours. The reaction mixture was added with water and extracted with ethyl acetate. The organic layer was washed with 1 mol/L hydrochloric acid, saturated aqueous sodium hydrogencarbonate solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by slurry using acetonitrile to obtain 5-[1-(tert-butoxycarbonyl)piperidine-4-carbonylamino]indole (142 mg, yield 55%).
