Reaction Steps
The crude tert-butyl (1S,2R)-2-(5-cyano-6-(1-methyl-1H-indol-4-ylamino)pyrazin-2-ylamino)cyclohexylcarbamate (153 mg) was dissolved in TFA (4 mL). After being stirred at room temperature for 2 h, the mixture was concentrated in vacuo. The residue was purified by HPLC to give 5-((1R,2S)-2-aminocyclohexylamino)-3-(1-methyl-1H-indol-4-ylamino)pyrazine-2-carbonitrile (18 mg).
