Procedure

4-(4-Aminobenzyl)phenyl-carbamic acid benzyl ester (0.997, 3 mmol) was added to a solution of phenylisocyanate (0.393 g, 3.3 mmol) in dichloromethane (20 mL). The reaction mixture was stirred for 1 hour at room temperature under nitrogen. The reaction mixture was quenched with water and concentrated in vacuo. The residue was suspended in water, filtered, washed with water, and dried to give {4-[4-(3-phenylureido)benzyl]phenyl}-carbamic acid benzyl ester (1.38 g) as a white solid.
