Procedure

To a mixture of ethyl 3-{[(6-{[cyclohexyl(5-fluoro-3-methyl-1-benzofuran-2-yl)methyl]amino}pyridin-3-yl)carbonyl](methyl)amino}propanoate (236 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 5 hr, and concentrated under reduced pressure. The residue was dissolved in water (10 mL), 1N hydrochloric acid (1.00 mL) was added at 0° C., and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure to give a pale-yellow solid. The obtained solid was recrystallized from ethyl acetate/hexane to give the title object compound (143 mg, 64%) as colorless crystals.
