Participants

Reaction Steps

A solution of tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (0.30 M in NMP, 1.00 mL, 0.300 mmol) in NMP (1 mL) was added to 2-(1H-benzo[d][1,2,3]triazol-1-yloxy)-4-(3-fluoro-4-(thiazol-4-yl)phenylamino)pyrimidine-5-carboxamide (12 mg, 0.027 mmol). DIEA (0.050 mL, 0.29 mmol) was also added. The mixture was stirred at 90 C for 1 h. After being cooled to room temperature, TFA (1 mL) was added. The solution was stirred at room temperature for 60 min. The mixture was purified by HPLC to give the titled compound (5 mg). MS 428.4 (M+H). UV λ=229.8, 313.8 nm.
