실험 절차

At 0° C. N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (558 mg, 2.91 mmol) was given to a solution of (2R)-2-(N-(tert-butoxycarbonyl)-N-methylamino)-3(2-naphthyl)propionic acid (959 g, 2.91 mmol) and 1-Hydroxy-7-azabenzotriazole (396 mg, 2.91 mmol) in N,N-dimethylformamide (5 ml) and dichloromethane (5 ml). The solution was stirred for 20 min at 0° C. A solution of 2-(2-(2-(Methylamino)ethyl)phenoxy)ethanol (608 mg, 2.91 mmol) in dichloromethane (5 ml) and ethyldiisopropylamine (0.50 ml, 2.91 mmol) were added successively. The reaction mixture was stirred for 16 h, while it was warming up to room temperature. It was diluted with ethyl acetate (150 ml) and washed with a 10% aqueous sodium hydrogen sulfate solution (70 ml). The aqueous phase was extracted with ethyl acetate (2×30 ml). The combined organic layers were washed with saturated sodium hydrogen carbonate soltuion (150 ml) and dried over magnesium sulfate. The solvent was removed in vacuo. The crude product was purified by flash chromatography on silica (110 g), using ethyl acetate/heptane (1: 1) as eluent, to give 1.02 g of N-((1R)-1-(N-(2-(2-(2-hydroxyethoxy)phenyl)ethyl)-N-methylcarbamoyl)2-(2-naphthyl)ethyl)-N-methylcarbamic acid tert-butyl ester.
