Versuchsvorschrift

2-Bromo-1-(2,4-Dichlorophenyl)-3-methyl-5-piperidin-1-yl-1,5,6,7-tetrahydropyrrolo[3,2-c]pyridine-4-one (450 mg, 0.98 mmol), 4-hydroxyphenylboronic acid (150 mg, 1.09 mmol) and tetrakis(triphenylphosphine)palladium(0) (150 mg) were dissolved in DME (20 ml) and 1 M Na2CO3 (5 ml)). The resulting solution was degassed and heated at 60° C. under nitrogen overnight. Water and EtOAc were added after cooling and the aqueous phase extracted with EtOAc (×3). The combined organic extracts were dried (Na2SO4), filtered and concentrated to give a crude product that was purified by flash chromatography (heptane:EtOAc gradient) to afford 0.40 g (87%) of the product as a pale yellow solid.
