PROCEDURE

实验过程

A solution of 1-[6-chloro-1-[4-(2-chloroethyl)phenyl]-5-(trifluoromethyl)-1H-benzimidazol-2-yl]ethanol (Example 367, step 1, 400 mg, 1 mmol) in CH2Cl2 was added MnO2 (2.7 g, 32 mmol) . The mixture was stirred at room temperature for 24 h. This was directly purified by flash column chromatography eluting with hexane/ethyl acetate (4:1) to afford 350 mg (88%) of the title compound as white solids.
