This compound was prepared in a manner similar to that shown in Scheme 3, using 5-bromo-6-methyl-1H-indazole as the starting material, which was prepared in a manner similar to that of 5-bromo-6-fluoro-1H-indazole. The starting material was treated with t-butyl lithium and carbon dioxide to yield 6-methyl-1H-indazole-5-carboxylic acid, which was in turn treated with thiosemicarbazide and polyphosphoric acid to form 94.
