The reaction mixture was shaken in an autoclave under a hydrogen pressure of 10 psi at ambient temperature for 16 h. The hydrogen pressure was released, the platinum(IV)oxide was filtered off and the filtrate was freed from solvent using the rotary evaporator. 0.14 g (0.28 mmol, 99%) (R)-1-(3-amino-4-benzyloxyphenyl)-2-[1,1-dimethyl-3-(4-phenylimidazol-1-yl)-propylamino]-ethanol was obtained as a brown oil.
