実験手順

To a solution of (2R)-2-(N-tert-butoxycarbonyl-N-methylamino)-3-phenylpropionic acid (0.27 g, 0.96 mmol) in methylene chloride (10 ml) was added 1-hydroxy-7-azabenzotriazole (0.13 g, 0.96 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (0.18 g, 0.96 mmol) and the mixture was cooled to 0° C. Then acetic acid N'-methylhydrazide (0.19 g, 0.96 mmol) and diisopropylethylamine (0.41 ml, 2.40 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 to give 0.35 g (125%) of crude N-[(1R)-2-(N'-acetyl-N-methylhydrazino)-1-benzyl-2-oxoethyl]-N-methylcarbamic acid tert-butyl ester as a colourless oil.
