実験手順

To a solution of 2-(carboxymethoxymethyl)piperidine-1-carboxylic acid tert-butylester (225 mg, 0.82 mmol) in 5 ml of dichloromethane was added 1-hydroxy-7-azabenzotriazole (112 mg, 0.82 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (173 mg, 0.90 mmol) and the mixture was to stired for 30 min. N-Methyl-2-methylamino-N-(1-methylcarbamoyl-2-phenylethyl)-3-(2-naphthyl)propionamide (332 mg, 0.82 mmol) in dichloromethane (5 mL) was added followed by diisopropylethylamine (0.14 ml, 0.82 mmol) and the mixture was stirred overnight at room temperature. The mixture was washed with water (5 ml) aqueous sodium bicarbonate (5 ml), water (2×5 ml), brine (5 ml), dried over magnesium sulfate and concentrated in vacuo. The crude product was chromatographed on silica (20 g) with ethyl acetate to give 416 mg of 2-([N-methyl-N-{(1R)-1-(N-methyl-N-[(1R)-1-(methylcarbamoyl)-2-phenylethyl]carbamoyl)-2-(2-naphthyl)ethyl}carbamoyl]methoxymethyl)piperidin-1-carboxylic acid tert-butyl ester.
