Reaction Steps

A mixture of 100 mg of tert-butyl [(1R)-1-(1-naphthyl)ethyl]{[(3R,4S)-4-phenylpyrrolidin-3-yl]methyl}carbamate, 53 mg of WSC hydrochloride, 37 mg of HOBt and 1.5 ml of methylene chloride was mixed with 51 mg of 4-(aminosulfonyl)benzoic acid and stirred at room temperature for 3Hours. The reaction solution was washed with water and then concentrated under a reduced pressure. The thus obtained residue was purified by a silica gel column chromatography (chloroform-methanol) to obtain 120 mg of tert-butyl ({(3R,4S)-1-[4-(aminosulfonyl)benzoyl]-4-phenylpyrrolidin-3-yl}methyl)[(1R)-1-(1-naphthyl)ethyl]carbamate as a pale yellow oily substance.
