Reaction Steps

A mixture of 6-bromo-1-chlorophthalazine (0.11 g, 0.5 mmol), N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (0.1 g, 0.5 mmol), and dichloro[1,1′-bis(diphenylphosphino)ferrocene]dichloride palladium(II) dichloromethane adduct (0.02 g, 0.02 mmol) in toluene (5 mL) was treated with 2 M aq. potassium carbonate (0.7 mL, 1 mmol). The mixture was stirred at 90° C. After about 15 hr, the mixture was cooled to RT and purified by flash chromatography (silica gel) eluting with 1/1 hexanes/ethyl acetate to 6% 2 M ammonia in MeOH/DCM to give the title compound as yellow solid. MS (ES+): 338 (M+H)+.
