Reaction Steps

To a solution of 5-fluoro-2-(1-isobutyl-1H-indazol-5-yloxy)-benzonitrile (3.05 g, 9.86 mmol) purged with N2 in MeOH (50 mL) was added concentrated HCl (1.6 mL) and Pd(OH)2/C (15% wt, 0.457 g). The mixture was stirred at room temperature for 18 hours under H2 atmosphere. The catalyst was removed by filtration and the solution was concentrated under reduced pressure to afford 3.32 g of pale yellow foam (96% yield).
