Procedure
To a solution of methyl 4′[2-[benzyl[(2R)-2-phenyl-2-(tetrahydro-2H-pyran-2-yloxy)ethyl]amino]ethyl]-3-nitro-4-biphenylcarboxylate (1.44 g) in ethanol (30 ml) and water (10 ml) were added iron (406 mg) and ammonium chloride (65 mg) and stirred under reflux for 1.5 hours. The mixture was filtrated through Celite pad and evaporated. The residue was dissolved with ethyl acetate, chloroform and methanol, washed with saturated sodium bicarbonate aqueous solution and brine, dried over magnesium sulfate and evaporated to give methyl 3-amino-4′-[2-[benzyl[(2R)-2-phenyl-2-(tetrahydro-2H-pyran-2-yloxy)ethyl]amino]ethyl]-4-biphenylcarboxylate (1.18 g).
