Procedure

The above 3-{4-[1-(1-cyclopropanecarbonylpiperidin-4-yl)-3-(4-trifluoromethoxyphenyl)ureidomethyl]benzoylamino}propionic acid methyl ester (0.17 g, 0.28 mmol) was dissolved in 10 mL ethanol and hydrolysed by adding lithium hydroxide (14 mg, 0.56 mmol) dissolved in water (1 mL). The mixture was stirred at 50° C. for 2 hours. The solvent was evaporated and water (25 mL) was added to the mixture followed by HCl (1N) adjusting pH to 3-4 allowing the title compound to be isolated as a precipitate.
