Versuchsvorschrift

To a solution of 6-(4-bromo-2-chloro-phenylamino)-7-fluoro-3-methyl-3H-benzoimidazole-5-carboxylic acid allyloxy-amide 29tt (20 mg, 0.04 mmol) in 0.50 mL 4:1 tetrahydrofuran/water is added OSO4 (41 μL, 0.054 M solution in t-BuOH, 0.002 mmol) followed by NMO (7 mg, 0.06 mmol). The solution is stirred at room temperature for eight hours after which time HPLC analysis showed complete conversion to product. The solution is then stirred with saturated NaHSO3 and diluted with ethyl acetate. The organic phase is dried (Na2SO4). Purification by FCC (DCM −>20:1 DCM/MeOH) provided 16 mg desired product as an off-white solid. MS ESI (+) m/z 487, 489 (M+, Br pattern) detected.
