5-(4-tert-Butoxycarbonylaminomethylpiperidin-1-yl)pentylamine (2.00 g) was dissolved in methylene chloride (80 ml) and phenyl isocyanate (0.80 ml) was dropwise added under ice-cooling. The mixture was stirred at room temperature for 15 hr, and the reaction mixture was concentrated under reduced pressure to give 4-tert-butoxycarbonylaminomethyl-1-(5-(3-phenylureido)pentyl)piperidine.
