Procedure

To a solution of the product from Step 1 (0.452 g, 1.45 mmol) in toluene (4 mL) were added 2-trifluoromethoxyphenylboronic acid (0.450 g, 2.18 mmol), tetrakis(triphenylphosphine)palladium (0.050 g, 3 mol %) and 2M sodium carbonate (1.45 mL, 2.9 mmol). The reaction was refluxed for 16 hours, then cooled and partitioned between EtOAc and water. The organic phase was washed with saturated sodium bicarbonate, brine and dried over sodium sulfate. The filtrate was concentrated in vacuo, and the crude product was purified by silica-gel chromatography using 4% EtOAc in hexanes to yield 0.42 g of the product (73% yield).
