To a suspension of 6-bromo-4-{[4-(4-methyl-piperazin-1-yl)-phenylamino]-methylene}-4H-isoquinoline-1,3-dione (221 mg, 0.5 mmol) in N,N-dimethylformamide (5 mL) is added 3-fluorobenzeneboronic acid (84 mg, 0.6 mmol), followed by 300 □L of 2M aqueous cesium carbonate and tetrakis triphenylphosphine palladium (30 mg, 0.06 mmol). The reaction mixture is subjected to microwave heating at 180° C. for 300 seconds. The reaction mixture is then diluted with N,N-dimethylformamide and purified by C18 reverse phase HPLC. The pure fractions were combined and concentrated to yield 6-(3-Fluoro-phenyl)-4-{[4-(4-methyl-piperazin-1-yl)-phenylamino]-methylene}-4H-isoquinoline-1,3-dione (65.2 mg).
