Reaction Steps

A mixture of (3Z)-3-[(4-bromophenyl)imino]-1-phenyl-1,3-dihydro-2H-indol-2-one (50.0 mg, 0.133 mmol), thiophene-3-boronic acid (26.0 mg, 0.199 mmol), tetrakis(triphenylphosphine)palladium(0) (31.0 mg, 0.0268 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), and concentrated. The crude product was purified by preparative TLC using 10% methanol in CHCl3, giving the desired product (18 mg, 35%).
