Patent number: 4921955Abstract: The invention relates to a process for the preparation of 1,5-disubstituted imidazoles of the formula ##STR1## by alkylation of an N-cyanoformamidine of the formula IIX--NH--CH.dbd.N--CH (II)to form an N,N-disubstituted N'-cyanoformamidine of the formula ##STR2## which is cyclised under the action of bases to form a 4-aminoimidazole of the formula ##STR3## and then reduced to form the product of the formula I. The invention relates also to a special process for the reduction of the aminoimidazole V to I, and to intermediate compounds for carrying out this process and to processes for the preparation of the intermediate compounds.The meaning of the substituents X and L is explained in detail in the text.Type: GrantFiled: December 18, 1987Date of Patent: May 1, 1990Assignee: Ciba-Geigy CorporationInventor: Werner Topfl
