실험 절차

At room temperature, 144 mg of WSC hydrochloride, 101 mg of HOBt, 215 mg of tert-butyl [(1R)-1-(1-naphthyl)ethyl]{[(3R,4S)-4-phenylpyrrolidin-3-yl]methyl}carbamate and 0.08 ml of triethylamine were added in that order to a mixture of 80 mg of monomethyl adipate and 5 ml of dichloromethane and stirred for 3 days, and then the reaction was quenched by adding water, and this was extracted with chloroform and washed with saturated brine. The organic layer was dried with anhydrous sodium sulfate and concentrated under a reduced pressure. The thus obtained residue was purified by a silica gel column chromatography (chloroform-methanol) to obtain 270 mg of methyl 6-[(3R,4S)-3-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpyrrolidin-3-yl)-6-oxohexanoate as a colorless amorphous substance. FP: 573.
