反応手順

To a solution of 1-methyl-6-nitro-1H-indazole (1.2 g, 0.7 mmol) in EtOH (50 ml) and THF (15 ml) was added PtO2 (125 mg) at 26° C. The mixture was stirred for 1.5 h at 26° C. under a H2 atmosphere at 30 Psi. Once the reaction was complete by TLC analysis, the mixture was filtered and the filtrate concentrated to give the target crude product as a white solid which was used in the next step without further purification (1.0 g, Yield 90%). LCMS (m/z): 148.1 (M+1).
