Procedure

To a mixture of 4-{[cyclohexyl(3-methylthieno[3,2-b]pyridin-2-yl)methyl]amino}benzoic acid (300 mg) synthesized in Example A144(5), ethyl 3-(methylamino)propanoate (155 mg), 1-hydroxybenzotriazole monohydrate (181 mg), triethylamine (329 μL) and N,N-dimethylformamide (10 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (226 mg), and the mixture was stirred at room temperature for 1 day. Saturated aqueous ammonium chloride solution was added to quench the reaction, and the reaction mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (50-100% ethyl acetate/hexane) to give the title object compound (325 mg, 84%) as a pale-yellow oil.
