Efficient and scalable chemical approaches to 3,5,7-trisubstituted 1H-indazoles were developed and applied to the synthesis of 1,1-dimethylethyl 4-[7-(aminocarbonyl)-5-bromo-1H-indazol-3-yl]-1-piperidinecarboxylate, a key intermediate for 3,5,7-trisubstituted 1H-indazole, which was identified as a potent IKK2 inhibitor. The sequence allows for a scalable preparation of the target compound in eight steps and proceeds in 40% overall yield from readily available starting material.
