Procedure
To a solution of 0.216 g (1.05 mmol) 1-ethyl-2-methyl-4-nitrobenzimidazole, 50 mL carbon tetrachloride and 0.375 g (2.11 mmol) NBS, was added 50 mg of AIBN. The reaction mixture was heated to 90° C. for five hours and the solution was cooled to room temperature. The solution was concentrated under reduced pressure and the resulting oil was chromatographed on silica to yield 0.16 g (0.57 mmol, 54%) of a light yellow oil.
