実験手順

To a solution of N-morpholinocarbonyl-L-phenylalanine (114 mg) and 2(S)-(L-histidyl)amino-1-cyclohexyl-3(S)-hydroxy-6-methylheptane (150 mg) in dry N,N-dimethylformamide (20 ml) which was cooled to 0° C., were added a solution of diphenyl phosphorylazide (125 mg) in dry N,N-dimethylformamide (5 ml) and triethylamine (46 mg). The mixture was stirred overnight at ambient temperature. After evaporation of the solvent, the residue was dissolved in ethyl acetate (30 ml) and the solution was washed with saturated sodium bicarbonate solution and water successively, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified with silica gel column chromatography (2% methanol in chloroform as eluent) to give 2(S)-(N-morpholinocarbonyl-L-phenylalanyl-L-histidyl)amino-1-cyclohexyl-3(S)-hydroxy-6-methylheptane (174 mg) as an amorphous powder.
