Procedure

To a mixture of ethyl 3-[{[4-({[5-(benzylamino)-3-methyl-1-benzofuran-2-yl](cyclohexyl)methyl}amino)phenyl]carbonyl}(methyl)amino]-propanoate (354 mg) synthesized above, tetrahydrofuran (5 mL) and ethanol (5 mL) was added 1N aqueous sodium hydroxide solution (2.00 mL), and the mixture was stirred at room temperature for 1.5 hr, and concentrated under reduced pressure. The residue was dissolved in water (10 mL), and 1N hydrochloric acid (2.00 mL) was added at 0° C. The resulting precipitate was collected by filtration to give the title object compound (310 mg, 92%) as a white solid.
