New type of 5-fluorobenzimidazole derivatives was synthesized through the reaction of 4-fluoro-5-(2,6-dimethylmorpholinyl)-2-aminoaniline with 5-nitro-2-furoic acid and 5-methoxy-3-chlorobenzothiophene-2-carboxylic acid in presence of PPA and treatment of $OH^-$. the resulting substituted 5-fluorobenzimidazole derivatives(6), (7) was characterized by high solubility in common polar organic solvents. We considered 5-fluorobenzimidazole derivatives were useful especially for antifungal drugs. These results are discussed from the viewpoints of the chemical and physical structures of the 5-fluorobenzimidazole derivatives.
