実験手順

To a mixture of 4-{[2-ethyl-1-(3-methyl-1-benzothiophen-2-yl)butyl]amino}benzoic acid (250 mg) synthesized above, β-alanine ethyl ester hydrochloride (157 mg), 1-hydroxybenzotriazole monohydrate (156 mg), triethylamine (284 μL) and N,N-dimethylformamide (10 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (196 mg), and the mixture was stirred at room temperature for 2.5 days. 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 brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (30-70% ethyl acetate/hexane) to give the title object compound (330 mg, quantitative) as a pale-yellow oil.
