Reaction Steps

A mixture of 6-bromo-1-(4-methylpiperazin-1-yl)phthalazine (0.13 g, 0.42 mmol), N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) benzamide (0.13 g, 0.42 mmol), tetrakis(triphenylphosphine)palladium (24mg, 0.021 mmol) and 2 M potassium carbonate (0.7 mL, 1.4 mmol) in 5 mL DME/EtOH (4: 1) was stirred at 90° C. for 2 h. The mixture was directly purified via flash chromatography (silica gel) eluting with a gradient of 2% 2 M ammonia in MeOH/DCM to 10% 2 M ammonia in MeOH/DCM to give the title compound (0.15g) as a yellow solid. Found MS (ES+): 402(M+H)+.
