Reaction Steps

A mixture of 2-(6-bromophthalazin-1-yl)-5-isopropyl-2,5-diaza-bicyclo[2.2.1]heptane (60 mg, 173 μmol), N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (52 mg, 173 μmol) and tetrakis(triphenylphosphine)palladium (10 mg, 9 μmol)in 5 mL DME/EtOH (4:1) was treated with 2M potassium carbonate (0.5 mL, 1 mmol) at 22° C. under nitrogen. The mixture was heated up to 90° C. and stirred for 1 h. The reaction was monitored by MS. After about 1 h at 90° C., MS showed all starting material was converted to product (M+1=442). The mixture was cooled down to room temperature (22° C.). The mixture was transferred directly to silica gel and purified via flash chromatography (silica gel) eluting with a gradient of 2% 2 M ammonia in MeOHIDCM to 6% 2 M ammonia in MeOH/DCM to give the title compound (60 mg). Found MS (ES+): 442(M+H)+.
