Reaction Steps

To a mixture of 4-{[cyclohexyl(5-fluoro-3-methyl-1-benzofuran-2-yl)methyl]amino}benzoic acid (1.06 g) synthesized above, ethyl 3-(methylamino)propanoate (438 mg), 1-hydroxybenzotriazole monohydrate (512 mg), triethylamine (930 μL) and N,N-dimethylformamide (20 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (640 mg), and the mixture was stirred at room temperature for 1.5 hr. 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 (55% ethyl acetate/hexane) to give the title object compound (564 mg, 41%) as a white solid.
