To a solution of 5-{2-[1-(tert-butyl-dimethyl-silanyloxy)-vinyl]-phenyl}-2-(4-trifluoromethyl-phenoxymethyl)-1H-benzoimidazole (0.126 g, 0.240 mmol) in CH2Cl2 (5 mL) at rt was added m-chloroperoxybenzoic acid (77% max, 0.161 g, 0.720 mmol). After stirring 1 hour, the reaction mixture was concentrated, and the residue was purified by chromatography (silica, hexanes: EtOAc, 2:1) to afford the title compound as a colorless oil (0.115 g, 94%).
