Reaction Conditions

Reaction Steps

534 mg of phenylboronic acid, 79 mg of palladium(II) acetate, 287 mg of 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl, 1.486 g of potassium phosphate (K3PO4) and 305 mg of 2-chloro-4-aminobenzonitrile were suspended in 7 ml of toluene and stirred at 80° C. under an argon atmosphere for 12 h. The cooled reaction mixture was admixed with water and ethyl acetate and filtered. The filtrate was extracted three times with a mixture of ethyl acetate and toluene. The organic phases were removed, dried over magnesium sulfate, filtered and concentrated under reduced pressure. 1H NMR: 7.52-7.42, m, 6H, 6.63, m, 2H, 6.25, s (broad), 2H.
