Procedure

To a mixture of ethyl 3-[{[4-({cyclohexyl[5-fluoro-3-(methoxymethyl)-1-benzofuran-2-yl]methyl}amino)phenyl]carbonyl}(methyl)amino]propanoate (197 mg) synthesized above, tetrahydrofuran (5 mL) and ethanol (5 mL) was added 1N aqueous sodium hydroxide solution (1.00 mL), and the mixture was stirred at room temperature for 7 hr, and concentrated under reduced pressure. The residue was dissolved in water (10 mL), and 1N hydrochloric acid (1.00 mL) was added at 0° C. The resulting precipitate was collected by filtration to give the title object compound (161 mg, 87%) as a pale-yellow solid.
