Procedure
A 124 mg portion of the ethyl 4-({[(3R,4S)-3-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpyrrolidin-1-yl]carbonyl}amino)benzoate obtained in Example 41 (1) was dissolved in 3.0 ml of ethyl acetate, and 1.0 ml of 4 M hydrogen chloride/ethyl acetate was added thereto and stirred overnight at room temperature. The reaction solution was concentrated under a reduced pressure, and the thus obtained residue was purified by a silica gel column chromatography (chloroform-methanol) to obtain 83 mg of ethyl 4-({[(3S,4S)-3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpyrrolidin-1-yl]carbonyl}amino)benzoate as a pale brown amorphous substance.
