実験手順

To a solution of 5-chloro-pyridine-2-carboxylic acid (13.2 mg, 85 μmol) in DMF (1 mL) was added HATU (32 mg, 85 μmol) and the resulting reaction mixture was stirred at room temperature for 30 minutes. 5-Ethyl-2-fluoro-4-[3-(1,4,5,6,7,8-hexahydro-imidazo[4,5-d]azepin-2-yl)-1H-indazol-6-yl]-phenol trihydrobromide salt (Preparation 32, 50 mg, 80 μmol) and DIPEA (56 μL, 320 μmol) were added and stirring was continued at room temperature for 18 hours. Saturated aqueous sodium hydrogen carbonate solution (5 mL) was added to the reaction mixture. The resulting solid was collected by filtration and washed with further saturated aqueous sodium hydrogen carbonate solution. The crude material was purified by HPLC Method A to afford 20.5 mg of the title compound.
