  • Patent number: 5359082
    Abstract: A process for the preparation of 4-substituted imidazoles of the general formula ##STR1## in which R denotes C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 cycloalkyl, aryl, and C.sub.7 -C.sub.20 aralkyl,whereina) N-formyl-.alpha.-aminonitriles of the general formula I ##STR2## in which R has the meanings stated above and A stands for carbonyl, are reacted, at a temperature ranging from to C. and a pressure ranging from 20 to 500 bar, with hydrogen in the presence of hydrogenation catalysts andb) the resulting N-formyl-1,2-diamines of the general formula ##STR3## in which R and A have the meanings stated above and n stands for 0 or 1, are reacted over a cyclization/dehydrogenation catalyst at a temperature ranging from to C. and a pressure ranging from 0.001 to 5 bar.
