실험 절차

A solution of 1.0 g of (E)-2(R)-[1(S)-(tert-butoxycarbonyl)-4-phenyl-3-butenyl]-4-methylvalerohydrazide in 10 ml of dimethylformamide was treated with 1.24 g of N-(9-fluorenylmethyloxycarbonyl)-glycine and 0.80 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride. The mixture was stirred overnight at room temperature and evaporated. The residue was dissolved in ethyl acetate and washed with 2M aqueous hydrogen chloride, 5% aqueous sodium hydrogen carbonate and saturated aqueous sodium chloride. Drying over anhydrous magnesium sulphate followed by evaporation and trituration with diethyl ether gave 1.54 g of (E)-2(R)-[1(S)-(tert-butoxycarbonyl)-4-phenyl-3-butenyl]-2′-[N-(9-fluorenylmethyloxycarbonyl)-glycinyl]-4-methylvalerohydrazide in the form of a white solid.
