Palladium-catalyzed amination reactions were carried out with 2-triflato-2'-(4methoxybenzyloxy)-1,1'-binaphthyl (5) and benzophenone imine followed by hydrolysis of the imine and hydrogenolysis of the benzyl protecting group to afford 2-amino-2'-hydroxy-1,1'binaphthyl (1). Arylamines were also coupl
