Reaction Conditions

Reaction Steps

A mixture of 3-(1-chlorophthalazin-6-yl)-N-cyclopropyl-4-methylbenzamide (100 mg, 296 μmol), o-tolylboronic acid (40 mg, 296 μmol) and tetrakis(triphenylphosphine)palladium (17 mg, 15 μmol) in 5 mL DME/EtOH (4:1) was treated with 2M potassium carbonate (444 μl, 888 μmol). The mixture was stirred at 90° C. for 2 h. The mixture was cooled to RT and purified directly without work-up, via flash chromatography (silica gel) eluting with a gradient of 2% 2 M ammonia in MeOH/DCM to 6% 2 M ammonia in MeOH/DCM to give the title compound in (65 mg) as a pale yellow solid. Found MS (ES+): 394(M+H)+.
