Reaction Steps

To a solution of N-((1R)-1-phenylethyl)[3-(4-methoxyphenyl)-4-methylphenyl]carboxamide (0.12 g, 0.34 mmol) in 10 mL of toluene was added DIBAL-H (1 mL, 1.5 mmol). The reaction was then heated to 100 C. for 16 hours and cooled to RT. The reaction was quenched with 5 mL of 2N NaOH aq. soln. 100 mL of CH2Cl2 was used to extract the product. The organic phase was washed with 30 mL of brine, dried over Na2SO3 and concentrated in vacuo. The desired products were separated by silica gel column chromatography (30% to 60% EtOAc in hexane) provide ((1R)-1-phenylethyl){[3-(4-methoxyphenyl)-4-methylphenyl]methyl}amine and 4-(5-{[((1R)-1-phenylethyl)amino]methyl}-2-methylphenyl)phenol, which were treated with 1N HCl in Et2O separately to provide the HCl salts as white solids.
