Prepared using the same procedure described in Example 410 from 6-(3-benzyl-piperazin-1-yl)-1-cyclobutyl-3-ethyl-1H-indazole and 2-chloro-6-nitro-pyridine to afford the intermediate 6-[3-benzyl-4-(6-nitro-pyridin-2-yl)-piperazin-1-yl]-1-cyclobutyl-3-ethyl-1H-indazole {20.5 mg; LC/MS (Method B) 5.09 min, [M+1]+ 497]}. The nitro-intermediate was reduced with sodium hydrosulfite (48 mg, 0.28 mmol) in 50:50 THF/water at room temperature to obtain the title compound as a tan solid (6 mg, 2% overall). LC/MS (Method B) 4.02 min, [M+1]+ 467.
