Trifluoroacetic acid → 2-amino-N-{6-cyano-5-[(4,6-dimethylpyridin-2-yl)-amino]pyridin-3-yl}ethanesulfonamide

Participants

Reaction Steps

To a solution of tert-butyl [2-({6-cyano-5-[(4,6-dimethylpyridin-2-yl)amino]pyridin-3-yl}sulfamoyl)ethyl]carbamate (100 mg, 0.22 mmol) in dichloromethane (1.8 mL) was added trifluoroacetic acid (0.26 mL, 3.4 mmol). The reaction mixture was stirred for 1 hour at room temperature. The reaction mixture was concentrated under reduced pressure to afford 2-amino-N-{6-cyano-5-[(4,6-dimethylpyridin-2-yl)amino]pyridin-3-yl}ethanesulfonamide, which was used without further purification. MS ESI calc'd. for C15H19N6O2S [M+H]+ 347. found 347.
