To a suspension of 1,1-dimethylethyl 5-(2-cyano-3-fluorophenyl)-2,3-dihydro-1H-indole-1-carboxylate (1.60 g, 4.73 mmol) in 30 mL of EtOH was added 7 mL of methylhydrazine in one portion. The mixture was heated in an oil bath at 100° C. for 24 h. LCMS showed conversion complete. The mixture was cooled and concentrated in vacuo. The residue was partitioned between DCM (60 mL) and water (30 mL). The organic was dried over Na2SO4, filtered, and concentrated in vacuo to give 1,1-dimethylethyl 5-(3-amino-1-methyl-1H-indazol-4-yl)-2,3-dihydro-1H-indole-1-carboxylate as a cream-colored foamy solid (1.70 g).
