Hexanoic the trunk decides method for the synthesis of

The invention discloses a synthetic method of hexamidine. Hexamidine is a key raw material for producing antibiotic medicines hexamidine salts (such as dihydrochloride and dihydroxyethyl sulfonate). The synthetic method of hexamidine comprises the following steps: 1, reacting p-cyanophenol with 1,6-dibromohexane in an ethanol-water solution of sodium hydroxide to prepare 1,6-(p-cyanophenyl)hexyl diether (an intermediate I); 2, carrying out alcoholysis on the intermediate I in ethanol-toluene under the catalysis of trifluoroacetic acid or methanesulfonic acid to prepare 1,6-(p-ethyl iminoformate phenyl)hexyl diether (an intermediate II); and 3, carrying out aminolysis on the intermediate II in a methanol-ammonia solution to prepare hexamidine. The total yield of three-step synthesis is greater than 72%, and a nuclear magnetism identification result shows that the above obtained product is a preconceived structure product. The method is suitable for large-scale industrial production.
