Versuchsvorschrift

0.74 g (3.4 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one, 1.0 g (3.2 mmol) (2,6-dichloro-pyridin-4-yl)-(5-fluoro-2,3-dihydro-indol-1-yl)-methanone and 0.65 mL (3.8 mmol) DIPEA in 10 mL DMF were stirred for 2 h at RT. Then the reaction mixture was evaporated down, the residue was mixed with water and stirred for 30 min at RT. The precipitated solid was suction filtered, stirred with diisopropylether and isopropanol and suction filtered again. After drying the crude product was purified by preparative HPLC-MS. The product-containing fractions were combined and freeze-dried.
