To a flask containing tert-butyl [(2S)-1-({6-cyano-5-[(4,6-dimethylpyridin-2-yl)amino]pyridin-3-yl}amino)propan-2-yl]carbamate (160 mg, 0.404 mmol) were added DCM (3 mL) and trifluoroacetic acid (0.3 mL). After 1 hour, the reaction mixture was concentrated under reduced pressure to afford 5-{[(2S)-2-aminopropyl]amino}-3-[(4,6-dimethylpyridin-2-yl)amino]pyridine-2-carbonitrile TFA salt. The material was used without further purification. MS ESI calc'd. for C16H21N6 [M+H]+ 297. found 297.
