Reaction Steps

91 mg (0.42 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one, 120 mg (0.42 mmol) 5-(6-chloro-pyrimidine-4-carbonyl)-7-methyl-1,3-dihydro-indol-2-one and 0.080 mL (0.46 mmol) DIPEA were combined in 2 mL DMF and shaken overnight at RT. Then the reaction mixture was in taken up acetonitrile/water and purified by preparative HPLC-MS. The fractions containing the product were combined and freeze-dried.
