Procedure

1-Methyl-3-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyridin-2-one (208 mg, 1 eq), Acetic acid 2-bromo-6-(6-tert-butyl-1-oxo-3,4-dihydro-1H-isoquinolin-2-yl)-benzyl ester (203 mg, 0.472 mmol), XPHOS (14 mg, 0.06 eq), potassium phosphate tribasic (200 mg, 2 eq), n-butanol (2.8 mL) and water (0.93 mL) were charged to a 50 mL round bottom flask, and then nitrogen gas was bubbled through the mixture for 10 minutes, before adding Pd(dba)2 (8 mg, 0.03 eq). The resulting mixture was heated to 100° C. for 40 minutes, and by TLC analysis there was no starting material remaining The reaction mixture was cooled to room temperature and then added ethyl acetate (150 mL) and water (40 mL). Partitioned and separated the layers and washed further with water (2×40 mL) and then brine (1×40 mL). Finally, the ethyl acetate layer was dried over magnesium sulfate, filtered and concentrated and pumped to dryness to afford the title compound which was used in the next step without any further purification ((M+H)+=664).
