    Type: Grant
    Filed: June 24, 1994
    Date of Patent: July 23, 1996
    Assignee: A/S Dumex (Dumex Ltd.)
    Inventors: Torben Koch, Hjarne Dyrsting
  • Patent number: 4424229
    Abstract: Fluorosubstituted benzaldehydes are condensed with anisil and ammonium acetate to yield the corresponding 2-(fluorosubstituted phenyl)-4,5-bis(4-methoxyphenyl)imidazoles. Alternatively fluorosubstituted benzaldehydes are condensed with anisil monoxime and ammonium acetate to yield the corresponding 2-(fluorosubstituted phenyl)-4,5-bis(4-methoxyphenyl)-imidazole-3-oxides which can subsequently be reduced to yield the corresponding 2-(fluorosubstituted phenyl)-4,5-bis(4-methoxyphenyl)imidazoles. These imidazoles have interesting pharmacological properties.
