A mixture of N-[5-(3,5-difluorobenzyl)-1H-indazol-3-yl]-4-nitro-2-[tetrahydro-2H-pyran-4-yl(trifluoroacetyl)amino]benzamide (3.86 g, 6.4 mmol), cyclohexene (10 mL), dioxane (70 mL) and 10% Pd/C (0.42 g) was stirred at 100° C. for 4 hours. The reaction mixture was filtered over a celite pad washing thoroughly with THF and MeOH. After evaporation of the organic phase, purification of the crude by chromatography over silica gel (DCM/EtOH 9/1) gave 2.75 g of title compound (82% yield).
