실험 절차

To a mixture of 4-{[cyclohexyl(6-fluoro-3-methyl-1-benzofuran-2-yl)methyl]amino}benzoic acid (350 mg) synthesized in Example A96(5), ethyl 3-(methylamino)propanoate (181 mg), 1-hydroxybenzotriazole monohydrate (211 mg), triethylamine (383 μL) and N,N-dimethylformamide (10 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (265 mg), and the mixture was stirred overnight at room temperature. 1N Hydrochloric acid was added to quench the reaction, and the 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% ethyl acetate/hexane) to give the title object compound (432 mg, 95%) as a yellow oil.
