実験手順

A solution of 1-tert-butyl-3,5-diiodo-2-methoxybenzene (4.94 g, 11.87 mmol) in dimethoxyethane (50 mL) and water (30 mL) was treated with 1-phenylvinylboronic acid (2.283 g, 15.43 mmol), tetrakis(triphenylphosphine)palladium(0) (0.686 g, 0.593 mmol) and sodium bicarbonate (2.492 g, 29.7 mmol) followed by heating at 100° C. for 3 hours. 1 N HCl was added and the mixture was extracted with ethyl acetate, then dried (Na2SO4), filtered and concentrated in vacuo to give crude product which was purified by silica gel flash chromatography eluting with 50:1 hexanes/ethyl acetate to give the title compound.
