反応手順
A mixture consisting of 50 mg of 2-(3-oxo-6-pyridin-4-yl-2,3-dihydropyridazin-4-yl)-3H-benzoimidazole-5-carboxylic acid, 0.065 ml of triethylamine and 1.5 ml of dimethylformamide (DMF) is stirred at room temperature for 10 minutes, mixed with 68.4 mg of O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (Hatu) and stirred at room temperature for a further 30 minutes. Then 21 mg of diethylaminoethylamine are added, and the mixture is stirred at 50° C. for 3 hours. After cooling, it is diluted with 5 ml of water, and the precipitate is filtered off with suction and stirred with isopropanol at 60° C., filtered off with suction and dried in vacuo.
