Versuchsvorschrift

A solution of tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (0.30 M in NMP, 2.00 mL, 0.600 mmol) in NMP (2 mL) was added to 2-(1H-benzo[d][1,2,3]triazol-1-yloxy)-4-(3-fluoro-4-(1H-pyrazol-1-yl)phenylamino)pyrimidine-5-carboxamide (184 mg, 0.427 mmol). DIEA (0.150 mL, 0.863 mmol) was also added. The mixture was stirred at 90 C overnight. After being cooled to room temperature, water was added to induce precipitation. The precipitate was collected, then dissolved in CH2Cl2 (5 mL) and TFA (4 mL). The solution was stirred at room temperature for 30 min. It was concentrated in vacuo. The residue was purified by HPLC to give the titled compound (103 mg). MS 411.5 (M+H). UV λ=238.8, 304.8 nm.
