The invention relates to the field of pharmaceutical chemistry, specifically to processes for preparing biologically active substances (BAS), in particular creatine amides. What is proposed is a process for preparing creatine amides which comprises treating creatine with para-toluenesulfonic acid in an organic solvent with subsequent reaction of the resultant complex with compounds comprising a primary or secondary amino group in the presence of a condensing agent and a base which are introduced subsequently. The claimed process makes it possible to increase the yield of the end product by 2-5 times in comparison with analogs and also to extend the range of the compounds prepared.
该发明涉及制药化学领域,具体涉及制备生物活性物质(BAS),特别是肌酸酰胺的过程。提出了一种制备肌酸酰胺的方法,包括将肌酸与对甲苯磺酸在有机溶剂中处理,然后将产生的复合物与含有一次或二次氨基团的化合物在缩合剂和碱的存在下进行反应,这些缩合剂和碱是随后引入的。所述方法可以使最终产品的产量比类似物增加2-5倍,并且还可以扩展所制备化合物的范围。
