Abstract
Procedure for obtaining new imidazoles of formula I **(See formula)** where one of the radicals R1 and R2 means hydrogen or lower alkyl and the other one means the nitro group, R3 means lower alkyl, hydroxyalkyl, lower alkoxy-lower alkyl, lower alkyl-sulfonyl-lower alkyl or aminoalkyl, R4 means oxo or thio, X signifies a carbonyl, thiocarbonyl, sulfinyl or sulfonyl group and, when X signifies a carbonyl group, R5 signifies lower alkoxy, amino, lower alkyl-amino or dialkyl lower amino, and when X signifies thiocarbonyl, sulfinyl or sulfonyl it means lower alkyl, aryl, amino, lower alkyl-amino or dialkyl lower-amino and "alk" means lower alkylene with 2-4 carbon atoms in the alkylene chain, its salts and N-oxides, characterized in that a) an imidazole of formula II **(See formula)** where R1, R2 and R3 have the meanings above and Z means an esterified hydroxy group, capable of reaction, an ethereal hydroxy group, capable of reaction, a free or ether mercapto group, an ammonium group or a sulfonyl group, is reacted with a compound of formula III **(See formula)** where R4, R5, X and alk have the meaning indicated above, or b) an imidazole of formula IV **(See formula)** where R3, R4, R5, X and alk have the meanings above, and one of the residues R'1 and R'2 means hydrogen or lower alkyl and the other one means hydrogen, is nitrated, or c) an imidazole of formula V **(See formula)** where R1, R2, R3, R4 and alk have the meanings indicated above, it is reacted with a compound of formula VI Z-X-R5 where X and R5 have the above meanings and Z means an esterified hydroxy group, capable of reaction, an ethereal hydroxy group, capable of reaction, a free or ether mercapto group, an ammonium group or a sulfonyl group, or d) an imidazole of formula VII **(See formula)** where R1, R2, R3, R4 and alk have the meanings indicated above, it is reacted with a compound of formula VIII H2N - X - R5 (VIII) where R5 and X have the meanings indicated in formula I and, if desired, substituents are introduced, modified or dissociated within the scope of the definition of the final products, and/or the racemate mixtures obtained are separated into the pure racemates., and/or the racemates obtained in the optical antipodes, and/or the salts obtained are transformed into the free compounds or into other salts or the free compounds obtained into their salts.
