Procedure

To 6-Bromo-1-morpholinophthalazine (0.20 g, 680 μmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium dichloride (50 mg, 68 μmol), potassium acetate (200 mg, 2040 μmol), and 4,4,5,5-tetramethyl-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,3,2-dioxaborolane (207 mg, 816 μmol) was added 1,4-dioxane (6.80 mL) and the mixture was heated to 80° C. for 2 h. The mixture was added to a sealed tube containing 4-chloro-3-iodobenzamide (230 mg, 816 μmol), tetrakis(triphenylphosphine)palladium (79 mg, 68 μmol), potassium carbonate—1.5 M in water (1.81 μl, 2.72 mmol), and ethanol (6.80 mL) and heated to 110° C. for 2 h. After cooling the reaction mixture was diluted with 75 mL of ethyl acetate, added to a separation funnel, partitioned with sodium bicarbonate (saturated, aqueous), washed 3 times with 50 mL of sodium bicarbonate (saturated, aqueous), separated, dried over sodium sulfate, concentrated in vacuo, and purified by HPLC to give the title compound.
