Procedure
Potassium carbonate (289 mg, 2.09 mmol) is added to a solution of acetic acid 4-[4-fluoro-2-methyl-1-(3-trifluoromethyl-phenylcarbamoyl)-1H-indol-5-yloxy]-pyrimidin-2-ylmethyl ester (1.05 g, 2.09 mmol) in MeOH (40 mL) at 23° C. The resulting mixture is stirred at 23° C. for 1 h. Saturated aqueous NH4Cl (50 mL) and water (20 mL) are added and the mixture is extracted with EtOAc (3×50 mL). The organic layers are combined, washed with brine (30 mL), dried (Na2SO4), and concentrated. The residue is purified by silica gel chromatography (10-100% EtOAc/heptane) to provide 4-fluoro-5-(2-hydroxymethyl-pyrimidin-4-yloxy)-2-methyl-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide.
