Procedure
To a solution of 600 mg of 2-[1-(2,4-Dichloro-phenyl)-4-methyl-5-(4-trifluoromethyl-phenyl)-1H-pyrazol-3-ylmethoxy]-2-methyl-propionic acid in 9 ml of DMF, 283 mg of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC), 271 mg of pentafluorophenol and 300 mg of NEM was added and the reaction mixture was stirred for 3 h at room temperature. Then, 278 mg of 4-Aminomethyl-benzoic acid and 424 mg of NEM in 10 ml of DMF were added. After 16 h the reaction mixture was diluted with water and filtered through a chem Elut® cartridge by eluting with ethyl acetate. The solvents were removed under reduced pressure and the residue was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1% TFA). The fractions containing the product were evaporated and lyophilized to yield a white solid. Yield: 204 mg.
