Procedure
A stream of nitrogen was passed through a suspension of the aryl bromide from Step 5 (65 mg), 4-(methylthio)phenylboronic acid (40 mg), 2 M Na2CO3 (0.22 mL) and DMF (1.0 mL) for 5 minutes. PdCl2dppf was then added and the reaction was warmed to 80° C. and stirred under nitrogen for 4 hours. The mixture was cooled to room temperature, diluted with ethyl acetate (20 mL) and poured into a saturated solution of sodium bicarbonate. The ethyl acetate layer was separated and the aqueous further extracted with ethyl acetate (2×15 mL). The combined ethyl acetate extracts were washed with brine and dried with magnesium sulfate. Removal of the solvent left a residue that was purified by chromatography on SiO2 using a gradient of hexanes and ethyl acetate (90:10 to 50:50) to afford the title compound.
