To a solution of methyl 4′-[2-(benzylamino)ethyl]-3-(isopropylamino)-4-biphenylcarboxylate (250 mg) in ethanol (15 ml) was added (R)-(+)-styreneoxide (142 μl) at room temperature, and the mixture was stirred under reflux for 48 hours. The mixture was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=3/1) to give methyl 4′-[2-[benzyl[(2R)-2-hydroxy-2-phenylethyl]amino]ethyl]-3-(isopropylamino)-4-biphenylcarboxylate (251 mg).
