Reaction Conditions

Reaction Steps

To dioxane (113 ml) is added 2-methoxy-5-fluorophenylboronic acid (4.25 g, 24.9 mmol), 2-bromothiophene (3.65 g, 22.7 mmol, 0.9 eq.) and potassium carbonate (2M, 37 ml). Palladium (0) tetrakistriphenylphoshine (0.03 eq.) is then added and the resulting mixture is heated to 85° C. for 3 hours. The reaction is cooled to room temperature and poured into ethyl acetate and water. The aqueous layer is extracted twice with ethyl acetate. The organic layers are combined, and dried over sodium sulfate, concentrated to a brown oil and the resulting residue is flash chromatographed in 20% toluene/hexanes to afford 11.5 g of 2-(thien-2-yl)-4-fluoroanisole (90%).
