314 mg (1.08 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one dihydrochloride were added to 300 mg (1.08 mmol) (4-chloropyridin-2-yl)-(5-fluoro-2,3-dihydro-indol-1-yl)-methanone and 373 mg (2.70 mmol) potassium carbonate in 5.0 mL N-methylpyrrolidone. The reaction mixture was stirred for 30 h at 130° C. Then the mixture was poured onto 100 mL water and extracted with EtOAc (3×100 mL). The combined organic phases were dried and evaporated down using the rotary evaporator. The residue was purified by preparative HPLC. The product fractions were combined and evaporated down i. vac. The residue was triturated with 30 mL diethyl ether. The precipitated solid was suction filtered and dried in the air.
