Disclosed are novel imidazole derivatives having the formula:
wherein R1 and R2 are H, alkyl, cycloalkyl, aryl, aralkyl or halogen-substituted alkyl, or R1 and R2 are combined to form a heterocyclic ring; R3, R4, R5 and R6 are H, halogen, alkoxy, aralkyloxy, alkyl, alkoxycarbonyl, nitro, amino, acyl, fluorine substituted-alkyl, or fluorine substituted-alkoxy, or R3 is combined with R2 to form a heterocyclic ring; R8 and R9 are H, halogen, alkoxy, alkyl, alkoxycarbonyl, nitro, amino, acyl, fluorine substituted-alkyl, fluorine substituted-alkoxy, or aryl group which may have a substitutent, or R8 and R9 are combined to form an alicyclic ring; R7 is, where R8 and R9 are not combined, H, and, where R8 and R9 are combined, H, alkyl which may have a substitutent, aryl which may have a substitutent, arylcarbonyl which may have a substitutent, or a sulfur-containing heterocyclic group; and n is 0 or 1. The new imidazole derivatives are effective particularly as anti-ulcer agents.
