Procedure

To a solution of 6-(4-bromo-2-methyl-phenylamino)-7-fluoro-3-(4-thiomorpholin-4-yl-butyl)-3H-benzoimidazole-5-carboxylic acid cyclopropylmethoxy-amide 181 (8 mg, 0.014 mmol) in 1:1:1 water/acetone/MeOH (1 mL) is added NMO (1.6 mg, 0.014 mmol) and osmium tetroxide (250 μL, 0.054 M solution in t-BuOH, 0.014 mmol). After stirring for 24 hours, the solution is diluted with saturated sodium thiosulfate, stirred for 10 minutes and diluted with ethyl acetate. The solution is washed with brine (2×), dried (Na2SO4) and concentrated under reduced pressure to a grey solid. FCC (10:1 dichloromethane/methanol) provides 6 mg (71%) desired product as an off-white solid. MS ESI (+) m/z 622, 624 (M+, Br pattern) detected.
