Versuchsvorschrift

6-(4-Bromo-2-chloro-phenylamino)-7-fluoro-3-methyl-3H-benzoimidazole-5-carboxylic acid 10c (2.00 g, 5.0 mmol), O-(2-vinyloxy-ethyl)-hydroxylamine (0.776 g, 7.5 mmol), HOBt (0.88 g, 6.5 mmol), triethylamine (1.61 mL, 2.3 mmol) and EDCI (1.3 g, 6.5 mmol) are dissolved in dimethylformamide (52 mL) and stirred at room temperature for 48 hours. The reaction mixture is diluted with ethyl acetate, washed with water (3×), saturated potassium carbonate (2×), saturated ammonium chloride (2×), brine, dried (Na2SO4) and concentrated under reduced pressure to an off-white solid. Trituration of the solid with diethyl ether provides 2.18 g (90%) desired product as an off-white solid. MS ESI (+) m/z 483, 485 (M+ Br pattern) detected.
