Reaction Steps

A mixture of tert-butyl 5-(6-bromophthalazin-1-yl)-2,5-diaza-bicyclo[2.2.1]heptane-2-carboxylate (0.18 g, 0.44 mmol), N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (0.14g, 0.44 mmol), tetrakis(triphenylphosphine)palladium (25 mg, 0.022 mmol) and 2 M potassium carbonate (0.66 mL, 1.32 mmol) in 5 mL DME/EtOH (4:1) was stirred at 90° C. for 2 h. The mixture was transferred directly to a column and purified via flash chromatography (silica gel) eluting with a gradient of 2% 2 M ammonia in MeOH/DCM to 10% 2M ammonia in MeOH/DCM to give tert-butyl 5-(6-(5-(cyclopropylcarbamoyl)-2-methylphenyl) phthalazin-1-yl)-2,5-diaza-bicyclo[2.2.1]heptane-2-carboxylate (0.20 g) as a yellow solid.
