実験手順
TFA (1.0 ml, 13 mmol) was added to a solution of tert-butyl (1S,2R)-2-(6-cyano-5-(6-methyl-4-phenylpyridin-2-ylamino)pyridin-3-ylamino)cyclohexylcarbamate (24 mg, 0.048 mmol) in DCM (2 ml). The reaction mixture was stirred for 30 minutes at room temperature. The reaction mixture was concentrated under reduced pressure to afford 5-((1R,2S)-2-aminocyclohexylamino)-3-(6-methyl-4-phenylpyridin-2-ylamino)picolinonitrile. The material was used in the next step without further purification. MS ESI calc'd. for C24H27N6 [M+H]+ 399. found 399.
