Ranney-Ni (20 mg) is washed with MeOH (3×5 mL) before a solution of (±)-5-[6-(cyano-trimethylsilanyloxy-methyl)-pyrimidin-4-yloxy]-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide (100 mg, 0.19 mmol) in MeOH (5 mL) and THF (3 mL) is added. The mixture is stirred under H2 atmosphere (ballon) overnight. The mixture is filtered through Celite® and the filtrate is concentrated. The residue is then separated by FCC (0-10% MeOH/EtOAc) to provide the title compound.
