Procedure

2-{5-[1-(3,5-Bis-trifluoromethyl-phenyl)-5-methyl-1H-pyrazol-4-ylmethoxy]-indol-1-yl}-2-methyl-propionic acid ethyl ester from step A in ethanol (2 mL) is added NaOH (5.0 M, 1 mL). After heated at 50° C. for 2 hrs, ethanol is evaporated. The residue is diluted with water, acidified with 5 N HCl, extracted with ether, dried over sodium sulfate. Concentration and purification by reversed phase HPLC (acetone/water/TFA as eluents) yields the title compound (60 mg). MS (ES): 525.96(M+−1); the structure is also confirmed by 1H NMR.
