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.
