Reaction Steps

To a solution of 2-iodo-3-(4-benzyloxyphenoxy)benzo[b]thiophene (5.00 g, 11.0 mmol) in 50 mL of toluene under N2 were added 3-methoxyphenylboronic acid (2.00 g, 13.0 mmol), (Ph3P)4Pd (0.75 g, 0.66 mmol), and 18.0 mL of 2.0 N Na2CO3 solution. The resulting mixture was heated to reflux for 2 h. Upon cooling to room temperature, the reaction was diluted with EtOAc and extracted several times with 0.1 N NaOH. The organic was then dried (Na2SO4) and concentrated in vacuo to an oil. Chromatography (SiO2, 0-10% Et2O/hexanes) provided 4.8 g (99%) of 2-(3-methoxyphenyl)-3-(4-benzyloxyphenoxy)benzo[b]thiophene as a brown oil.
