Reaction Steps
1-(3-Fluorobenzyl)-5-nitro-1H-indazole from Example 7A (500 mg) was dissolved in ethanol (40 mL) and was hydrogenated in an H-Cube™ (room temperature, 1 bar, 1 mL/min, 10% Pd/C catalyst). After removal of the solvent and trituration with tert-butyl methyl ether, 287 mg (64%) of the title compound were obtained.
