Procedure
To a mixture of ethyl 3-{[(4-{[cyclohexyl(6-methoxy-2-methyl-1-benzofuran-3-yl)methyl]amino}phenyl)carbonyl](methyl)amino}propanoate (781 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 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 (702 mg, 95%) as a white solid.
