Participants

Reaction Steps

A mixed solution of 264 mg of ethyl (4-{[(3R,4S)-3-({(tert-butylcarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpyrrolidin-1-yl]carbonyl}phenoxy)acetate and 3.0 ml of 1,4-dioxane was mixed with 1.0 ml of 4 M hydrogen chloride/1,4-dioxane and stirred at room temperature for 24Hours. The reaction solution was concentrated under a reduced pressure, and the residue was purified by a silica gel column chromatography (chloroform-methanol) to obtain 174 mg of ethyl (4-{[(3S,4S)-3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpyrrolidin-1-yl]carbonyl}phenoxy)acetate as a colorless amorphous substance. FP: 537.
