Procedure
A solution of 4-(cyclohexyl{2-(methoxymethyl)-5-[4-(trifluoromethyl)phenyl]furan-3-yl}methoxy)benzoic acid (98 mg), ethyl 3-(methylamino)propanoate (31 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (46 mg), hydroxybenzotriazole monohydrate (37 mg) and triethylamine (33 μL) in N,N-dimethylformamide (10 mL) was stirred at room temperature for 4 hr. Ethyl acetate was added, the mixture was washed with saturated aqueous sodium hydrogen carbonate solution and 1N hydrochloric acid, and the organic layer was dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the organic layer was dried over magnesium sulfate. The solvent was evaporated under reduced pressure. To the residue were added ethanol (2 mL), tetrahydrofuran (2 mL) and 1N lithium hydroxide (0.5 mL), and the mixture was stirred at room temperature for 1 hr. The solvent was evaporated under reduced pressure, and water (10 mL) was added. The mixture was neutralized with 1N hydrochloric acid under ice-cooling, and stirred for 1 hr. The resulting precipitate was collected by filtration and dried to give the title compound (93 mg, 81%).
