実験手順
Serotonin hydrochloride (300 mg, 1.41 mmol) and trans-2,4-dihydroxycinnamic acid (253 mg, 1.41 mmol) were dissolved in a mixed solvent of dichloromethane (6 ml) and N,N-dimethylformamide (6 ml), and the solution was maintained at 0° C. To this solution were added triethylamine (216 μl, 1.55 mmol), 1-hydroxybenzotriazole hydrate (HOBt H2O, 237 mg, 1.55 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDCI HCl, 297 mg, 1.55 mmol), and the mixture was gradually warmed to room temperature and stirred at room temperature for 16 hours. The solvent was removed under reduced pressure, water (10 ml) was added to the residue, and the mixture was extracted twice with ethyl acetate (10 ml). The ethyl acetate layer was washed twice with 5% aqueous citric acid solution (5 ml), once with saturated brine (5 ml), twice with 5% aqueous sodium hydrogen carbonate solution (5 ml), and once with saturated brine (5 ml), and dried over anhydrous magnesium sulfate. Magnesium sulfate was removed by filtration, and the filtrate was concentrated under reduced pressure, and purified by preparative thin-layer chromatography (PTLC, eluent: ethyl acetate-n-hexane=2:1, 0.01% formic acid) to give N-[2-(5-hydroxy-1H-indol-3-yl)ethyl]-3-(2,4-dihydroxyphenyl)-2-propenamide (243 mg, yield 51.0%) as a viscous oil.
