실험 절차

In N,N-dimethylformamide (5 ml) is dissolved 3-(o-aminophenyl)thio-2(R)-[5-(1-benzyloxycarbonyl-4-piperidyl)-1-ethoxycarbonylpentyl]aminopropionic acid dihydrochloride (0.16 g), and diethyl phosphorocyanidate (0.3 ml) is added dropwise to the solution. To the mixture is added triethylamine (0.2 ml) and the reaction mixture is stirred under ice-cooling for 1 hour. The reaction mixture is diluted with water (100 ml) and extracted with ethyl acetate (50 ml). The extract is washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue is purified by silicagel column chromatography (hexane: acetone=2:1) to give 3(R)-[5-(1-benzyloxycarbonyl-4-piperidyl)-1-ethoxycarbonylpentyl]amino-2,3-dihydro-1,5(5H)-benzothiazepin-4-one (0.09 g) as a colorless oil.
