Reaction Steps

0.26 g (0.9 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one dihydrochloride, 0.30 g (0.9 mmol) (2-chloro-6-methoxy-pyridin-4-yl)-(5-fluoro-3,3-dimethyl-2,3-dihydro-indol-1-yl)-methanone and 0.37 g (2.7 mmol) potassium carbonate were stirred in 3 mL NMP for 12 h at 130° C. The reaction mixture was purified by HPLC. The product-containing fractions were combined and freeze-dried.
