标 题 :Process for the synthesis of 1-substituted imidazole-5-carboxylic acids and carboxylic acid derivatives
发明人：TOEPFL WERNER
权利人:CIBA GEIGY CORP
摘要:The invention relates to a process for the preparation of 1,5-disubstituted imidazoles of the formula (I) by alkylation of an N-cyanoformamidine of the formula II X-NH-CH=N-CH (II) to form an N,N-disubstituted N'-cyanoformamidine of the formula (IV) which is cyclised under the action of bases to form a 4-aminoimidazole of the formula (V) 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.
