Procedure

A mixture of (3z)-5-bromo-1-phenyl-3-{[3-(trifluoromethyl)phenyl]imino}-1,3-dihydro-2H-indol-2-one (22 mg, 0.05 mmol), tetrakis(triphenylphosphine)palladium(0) (12.0 mg, 0.01 mmol), benzene boronic acid (10 mg, 0.08 mmol) in THF (5 mL), and aqueous Na2CO3 (2M, 100 μL) was heated at 67° C. for 24 h. The crude product was concentrated in vacuo and the residue was extracted with CH2Cl2 (3×1 ml), concentrated, and purified by preparative TLC using 10% methanol in CHCl3, giving the desired product (4 mg, 18%).
