Versuchsvorschrift

To a mixture of 4-{[1-(5-methoxy-3-methyl-1-benzofuran-2-yl)-5-(methylsulfanyl)pentyl]amino}benzoic acid (460 mg) synthesized in Example A120(4), ethyl 3-(methylamino)propanoate (219 mg), 1-hydroxybenzotriazole monohydrate (256 mg), triethylamine (464 μL) and N,N-dimethylformamide (10 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (320 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 (30-50% ethyl acetate/hexane) to give the title object compound (514 mg, 88%) as a pale-brown oil
