Procedure

[6-(5-Chloro-pyridazin-3-ylamino)-pyridin-3-yl]-morpholin-4-yl-methanone (200 mg, 0.63 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 (470 mg, 1.25 mmol) and K2CO3 (173 mg, 1.25 mmol) were dissolved in dioxane/H2O (10:1, 11 ml). Under N2 atmosphere, Pd2(dba)3 (58 mg, 0.063 mmol) and X-phos (120 mg, 0.25 mmol) were 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 (240 mg, yield 59%). LC-MS: 652[M+1]+, tR=1.459 min.
