Procedure

To a mixture of ethyl 3-{[(4-{[cyclohexyl(6-methoxy-1-methyl-1H-benzimidazol-2-yl)methyl]amino}phenyl)carbonyl](methyl)amino}propanoate (103 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 2 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 (72.1 mg, 74%) as a pale-brown solid.
