6-Bromo-N-(2-(diethylamino)ethyl)phthalazin-1-amine (140 mg, 430 μmol), potassium acetate (60 mg, 610 μmol), bis(pinacolato)diboron (150 mg, 610 μmol), and 1,1′-bis(diphenylphosphino)ferrocene-palladium dichloride (32 mg, 40 μmol) were suspended in dioxane (4 mL) and heated in the microwave for 10 min at 160° C. The reaction was added to a mixture of 3-bromo-N-cyclopropyl-4-methylbenzamide (110mg, 430 μmol), sodium carbonate-2 M in water (0.33 mL, 0.65 mmol), tetrakis(triphenylphosphine)palladium (50 mg, 40 μmol), and ethyl alcohol (5 mL), the combination of which was heated in the microwave for 10 min at 160° C. The reaction mixture was diluted with 20 mL of EtOAc, added to an addition funnel and partitioned with sodium bicarbonate (saturated, aqueous). The organic layer was washed 3 times with 20 mL of sodium bicarbonate (saturated, aqueous), dried over sodium sulfate, and concentrated via rotovap to give crude product. The crude was purified by chromatography to obtain the title compound. Found MS (ES+): 418(M+H)+.
