Procedure
A solution of methyl 2-(1H-indazol-6-ylamino)-6-((1R,2S)-2-(tert-butoxycarbonylamino)cyclohexylamino)-4-cyanonicotinate (110 mg, 0.218 mmol) and TFA (2 mL, 26.9 mmol) in DCM (1 mL) was stirred at room temperature for 3 h. Following reaction, the mixture was concentrated in vacuo to give the title compound, which was used in the next step without further purification.
