To a solution of aryl bromide of Example 7 (50.7 g, 0.10 moles) in toluene (250 ml) was added (2-sulfanylphenyl)methanol (16.8 g, 0.12 moles), sodium (tert)-butoxide (14.4 g, 015 moles) and [1,1′-bis(diphenylphosphino)ferrocene]dichloro palladium (II) (0.41 g, 0.0005 moles). The resultant mixture was sparged with nitrogen for 10 minutes then heated at 111° C. for 16 hours. The reaction was cooled to 20° C., diluted with isopropyl acetate (200 ml) and washed with 2M hydrochloric acid solution (250 ml). The aqueous phase was extracted with isopropyl acetate (50 ml) and the combined organics were washed sequentially with 1M sodium hydroxide solution (250 ml) and 10% w/w sodium chloride solution (250 ml). The solvent was distilled under reduced pressure and replaced with (tert)-butyl methyl ether to give a final volume of 250 ml. The solution was cooled to 5° C. and granulated for 5 hours, then solid was collected by filtration to give the title compound as a white solid (38.5 g, 68%).
