実験手順

3-Aminopropan-1-ol (0.39 mL, 5.12 mmol) was added at room temperature to a solution of N-tert-butoxycarbonyl-N-methyl-D-phenylalanine (1.30 g, 4.65 mmol) in N,N-dimethylformamide (40 mL). 1-Hydroxybenzotriazole monohydrate (0.63 g, 4.65 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.89 g, 4.65 mmol) were added successively. The reaction mixture was stirred for 22 h at room temperature. It was diluted with 1 0% sodium hydrogensulfate solution (300 mL) and extracted with ethyl acetate (4×100 mL). The combined organic layers were dried over magnesium sulfate. The solvent was removed in vacuo and the crude product was purified by flash chromatography on silica (45 g) with dichloromethane/methanol (10:1) to give 1.01 g of N-((1R)-1-(3-hydroxypropylcarbamoyl)-2phenylethyl)-N-methylcarbamic acid tert-butylester.
