Reaction Steps

0.59 g (2.7 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one, 0.80 g (2.7 mmol) (2-chloro-pyridin-4-yl)-(4,5-difluoro-2,3-dihydro-indol-1-yl)-methanone and 0.39 g (2.8 mmol) potassium carbonate were stirred in 3 mL of NMP for 4 h at 130° C. The reaction mixture was purified by HPLC. The product-containing fractions were combined and freeze-dried.
