Procedure

To a mixture of 4-{[cyclohexyl(3-methylthieno[3,2-c]pyridin-2-yl)methyl]amino}benzoic acid (211 mg) synthesized above, β-alanine ethyl ester hydrochloride (128 mg), 1-hydroxybenzotriazole monohydrate (128 mg), triethylamine (233 μL) and N,N-dimethylformamide (10 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (160 mg), and the mixture was stirred overnight at room temperature. 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 (60-100% ethyl acetate/hexane) to give the title object compound (214 mg, 80%) as a white solid.
