実験手順

To a solution of (2E)-5-(tert-butyloxycarbonylamino)-5-methylhex-2-enoic acid (0.066 g, 0.27 mmol) in methylene chloride (5 ml) was added 1-hydroxy-7-azabenzotriazole (0.037 g, 0.27 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.052 g, 0.27 mmol) and the mixture was cooled to 0° C. Then (2R)-N-[(1R)-2-(N'-acetyl-N-methylhydrazino)-1-benzyl-2-oxoethyl]-N-methyl-2-(methylamino)-3-(2-naphthyl)propionamide (0.10 g, 0.22 mmol) and diisopropylethylamine (0.049 ml, 0.29 mmol) were added and the mixture was stirred at room temperature overnight. Then methylene chloride (50 ml) was added and the mixture was washed with water (10 ml), saturated sodium bicarbonate (10 ml), brine (10 ml), dried (MgSO4), filtered and concentrated in vacuo. The product was chromatographed on silica gel (40 g) with heptane:ethyl acetate (1:1) to give 0.10 g (66%) of ((3E)-4-[N-((1R)-1-(N-[(1R)-2-(N'-acetyl-N-methylhydrazino)-1-benzyl-2-oxoethyl]-N-methylcarbamoyl)-2-(2-naphthyl)ethyl)-N-methylcarbamoyl]-1,1-dimethylbut-3-enyl)carbamic acid tert-butyl ester as a colourless oil.
