Procedure

Ethyl 3-(4-Aminomethylbenzoylamino)propanoate hydrochloride (0.25 g, 0.87 mmol) in acetonitrile (5 mL) and diisopropylethylamine (0.15 mL) was allowed to react with 4-trifluoromethoxyphenylisocyanate (0.37 g, 1.74 mmol) at 50° C. overnight. Upon cooling to 25° C. the product precipitated and was collected by filtration.
