Reaction Steps

Copper(II)acetate (26 mg), 4-cyanomethoxy-phenylboronic acid pinacol ester (CAS Reg. No. 475272-13-0, 38 mg), and DMAP (30 mg) were added to a solution of 5-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1,3-dimethyl-1,3-dihydro-benzoimidazol-2-one (Example 85, 20 mg) in acetonitrile (3 ml). The mixture was stirred with molecular sieves under air atmosphere for 4 h at 80° C., and then filtered over Celite concentrated to an oil. The residue was purified by prep. HPLC (C18-column, solvent gradient 20-98% CH3CN in 0.1% HCOOH[aq]) to give the title compound (24 mg) as a white solid. MS (m/e)=546.1 [M+H+].
