Reaction Steps

To 138 mg of [(tert-butoxycarbonyl){2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-2-oxoethyl}amino]acetic acid was added 2.0 mL of a 4 M hydrogen chloride/1,4-dioxane solution. After stirring at room temperature for 2 hours, the reaction mixture was concentrated under reduced pressure, and to the obtained residue were added isopropanol and diisopropylether, and the precipitated solid was collected by filtration to obtain 83.9 mg of ({2-[4-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-2-oxoethyl}amino)acetic acid hydrochloride as a white solid.
