This compound has unique chemical properties. The synthetic route is as follows.
A mixture of 368 mg (1 equiv) of tert-butyl 2-(5-bromo-3-carbamoyl-1H-indazol-1-yl)acetate (112), pyrimidin-5-amine (95 mg, 1 equiv), and cesium carbonate (650 mg, 2 equiv) in DMF (20 mL) was purged with argon in a pressure vessel for 5 min, then tris(dibenzylideneacetone) dipalladium(O) (0.01 equiv) and 4,5-bis(diphenylphosphino)-9,9- dimethylxanthene (0.01 equiv) were added under argon. The pressure vessel was sealed and heated at 100 C for 24 h. The reaction mixture was then cooled to rt and the solvent was removed under reduced pressure. The remaining residue was purified by flash column chromatography (eluted with DCM/CH3OH) to give tert-butyl 2-(3-carbamoyl-5-(pyrimidin-5-ylamino)-1H-indazol-1-yl) acetate (113).
