Procedure

To a solution of {6-[1-(5-tert-Butyl-isoxazol-3-ylcarbamoyl)-4-fluoro-2-methyl-1H-indol-5-yloxy]-pyrimidin-4-ylmethyl}-methyl-carbamic acid tert-butyl ester (0.25 g, 0.452 mmol) in DCM (10 mL) is added TFA (1.5 mL). After 3 h the solvent is removed by rotary evaporation and the residue is diluted with DCM and water. Concentrated NH4OH is added to neutralize and the aqueous phase is extracted twice with DCM. The organic layers are washed with brine, dried over Na2SO4, and concentrated to give the title compound.
