실험 절차

A 2.0 ml THF solution of 253 mg of 4-(methoxycarbonyl)phenyl(3S,4S)-3-(aminomethyl)-4-phenylpyrrolidine-1-carboxylate and 144 mg of 5-acetylbenzodioxane was mixed with 0.12 ml of a boron trifluoride diethyl ether complex at 0° C. 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 chromatography (chloroform-methanol) to obtain 146 mg of 4-(methoxycarbonyl)phenyl(3S,4S)-3-({[1-(2,3-dihydro-1,4-benzodioxin-5-yl)ethyl]amino}methyl)-4-phenylpyrrolidine-1-carboxylate as a colorless amorphous substance. EP: 517.
