METHOD OF OBTAINING NOVEL DERIVATIVES OF BENZIMIDAZOLE

The novel compounds of the formula I I and physiologically acceptable salts thereof, wherein R1 and R2, which are different is each H alkyl containing 1-4 carbon atoms or -C(O)-R5; wherein R5 is alkyl containing 1-4 carbon atoms or alkoxy containing 1-4 carbon atoms and one of R1, or R2 is always selected from the group -C(O)-R5; R3 and R4 are the same or different and selected from ith the adjacent oxygen atoms atached to the pyridine ring and the carbon atoms in the pyridine ring form a ring, wherein the part constituted by R3 and R4 is -CH2CH2CH2-, or -CH2-CH2- or -CH2-; as well as intermediates, pharmaceutical compositions containing such compounds as active ingredient and the use of the compounds in medicine.
