Procedure

To a mixture of ethyl 3-[{[4-({cyclohexyl[3-methyl-6-(trifluoromethyl)thieno[3,2-b]pyridin-2-yl]methyl}amino)phenyl]carbonyl}(methyl)amino]propanoate (310 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), 1N hydrochloric acid (2.00 mL) was added at 0° C. The resulting precipitate was collected by filtration to give the title object compound (284 mg, 96%) as a white solid.
