A mixture of 4-[4-(3-phenylureido)benzyl]phenyl-carbamic acid benzyl ester (1.3 g) and 10% palladium on carbon (0.35 g) in ethanol (150 mL) was hydrogenated at 50 psi in a Parr apparatus for 12 hours. The reaction mixture filtered through a Celite pad to remove catalyst. The filtrate on concentration gave 4-[4-(3-phenylureido)benzyl]-phenylamine (0.76 g) as white solid.
