Procedure

[6-(4-Bromo-pyridin-2-ylamino)-pyridin-3-yl]-morpholin-4-yl-methanone (200 mg, 0.55 mmol), acetic acid 2-(6-tert-butyl-8-fluoro-1-oxo-1H-phthalazin-2-yl)-6-(4,4,5,5-tetramethyl[1,3,2]dioxaborolan-2-yl)-benzyl ester (410 mg, 0.83 mmol) and K2CO3(152 mg, 1.10 mmol) were dissolved in dioxane/H2O (10:1, 11 ml). Under N2 atmosphere, Pd2(dba)3 (50 mg, 0.055 mmol) and X-phos (105 mg, 0.22 mmol) was added and the mixture was stirred at reflux temperature overnight. After the completion of the reaction, the mixture was cooled to room temperature and filtered. The organic layer was washed with saturated brine, dried over sodium sulfate and concentrated. The residue was purified by silica gel column (petroleum ether:ethyl acetate=2:1). The desired product was obtained as a yellow solid (200 mg, yield 56%). LC-MS: 651[M+1]+, tR=1.397 min.
