Procedure
To a solution of 2-(dimethylamino)-6-nitro-1H-benzimidazole-4-carboxylic acid (520 mg) and HBTU (1.03 g) in DMF (6 mL), were added N,N-diisopropylethylamine (942 μL) and 3-chloro-2-methylaniline (323 μl), and the mixture was stirred at room temperature for 15 hours. The reaction mixture was diluted with ethyl acetate-THF (1:1), washed with brine, and the organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was washed with MeOH to obtain the titled compound (650 mg) as a yellow solid.
