Procedimiento

0.25 g (0.89 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one dihydrochloride, 0.34 g (0.89 mmol) N-[6-chloro-4-(5-fluoro-2,3-dihydro-indole-1-carbonyl)-pyridin-2-yl]-N-methyl-methanesulphonamide and 0.37 g (2.7 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 acetonitrile was eliminated by rotary evaporation. The precipitated substance was suction filtered and dried.
