Reaktionsschritte

To a solution of 4-(4-amino-2,5-difluorophenoxy)picolinamide (200 mg, 0.76 mmol), and 1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid (165 mg, 0.75 mmol) in DCM (10 mL) was added EDCI (175 mg, 0.93 mmol), and HOAT (26 mg, 0.15 mmol). The reaction was stirred at 45° C. for 16 hours, cooled to rt and diluted with EtOAc (20 mL). The solid was collected through filtration, dried at 45° C. in vacuo overnight to give the title compound as a white solid (230 mg, 63.7%).
