3-bromo-5-methoxybenzonitrile (8.3 g, 39.1 mmol), dicyclohexyl(2′,6′-dimethoxy-[1,1′-biphenyl]-2-yl)phosphine (S-Phos) (1.286 g, 3.13 mmol), phenylboronic acid (5.84 g, 47.0 mmol), Pd2(dba)3 and 200 mL toluene were charged in a flask and refluxed overnight. The reaction was cooled down and 200 mL of ethyl acetate was added. The crude mixture was run though a silica gel plug, and the product was confirmed by GC. After distillation under vacuum, 7.5 g of a white product was obtained.
