Synthesis of 2-Substituted 5 (6)-Aroylaminobenzimidazoles as potential Anthelmintics

A series of alkyl 5(6)-aroylaminobenzimidazol-2-carbamates (22-35), 2-(substituted-aryl)-5 (6)-aroylaminobenzimidazoles (36-42) and 2-trifluoromethyl-5 (6)-(nicotinoylamino)benzimidazol (43) have been prepared starting from 4-aroylamino-o-phenylenediamine

Process for the manufacture of benzimidazolones-(2)

Process for the manufacture of benzimidazolones-(2) wherein an o-phenylenediamine is reacted with optionally alkylated urea in the ratio of 1 to 1.3 moles per mole o-phenylenediamine in an organic solvent which has a solubility in water of not more than 5 g/l and has a boiling point above 100° C, at a temperature between 100° and 200° C.
