Trypanosomacruzi and Trypanosoma brucei are the parasitic causative agents of Chagasdisease and human African trypanosomiasis (HAT), respectively. The drugs currently used to treat these diseases are not efficacious against all stages and/or parasite sub-species, often displaying side effects. Herein, we report the SAR exploration of a novel hit, 2-(4-chlorophenyl)-N-(1-propyl-1H-benzimidazol-2-yl)acetamide
The present invention relates to novel benzimidazole derivatives, their preparation, their use as pharmaceuticals and pharmaceutical compositions containing them, wherein the compounds have the formula (I):

Efficient One-Pot Conversion of 6-Methyl-2-nitroaniline into 1-Alkyloxy-2-alkyl-4-methyl-, 1-Benzyloxy-2-phenyl-4-Methyl-, and 1-Allyloxy-4-methyl-2-vinyl-benzimidazole

6-Methyl-2-nitroaniline reacts with alkyl, benzyl and allyl halides and NaH as base, to afford 1-alkoxy-2-alkyl-, 1-benzyloxy-2-aryl- and 1-allyloxy-2-vinyl-benzimidazoles in good to excellent yields (73-98%), via a novel one-pot N-alkylation-heterocyclization-O-alkylation sequence.
