実験手順: 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. The mixture was added to a sealed tube heated to 110° C. for 2 h After cooling the reaction mixture 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 purified by HPLC

実験手順: 4-chloro-3-iodobenzoic acid (2.09 g, 7.40 mmol) was suspended in thionyl chloride (0.540 mL, 7.40 mmol) and heated to 70° C. for 3 h before it was concentrated and azeotropically dried with toluene. The concentrate was dissolved in ammonia, 0.5 M in 1,4-dioxane (92.5 mL, 37.0 mmol) to which diisopropylethylamine (6.44 mL, 37.0 mmol) was added and it was stirred at RT for 3 h. The mixture was diluted with 100 mL of ethyl acetate, added to a separation funnel, partitioned with sodium bicarbonate (saturated, aqueous), washed 4 times with 50 mL of sodium bicarbonate (saturated, aqueous), separated, dried over sodium sulfate, and concentrated in vacuo to give the title compound. MS (ES+): 282 (M+H)+. was concentrated azeotropically dried with toluene The concentrate was dissolved in ammonia added to a separation funnel partitioned with sodium bicarbonate (saturated, aqueous) washed 4 times with 50 mL of sodium bicarbonate (saturated, aqueous) separated dried over sodium sulfate concentrated in vacuo
