| titleOfInvention | Preparation method of isoproterenol hydrochloride |
| abstract | The invention relates to the technical field of raw material medicine synthesis, in particular to a preparation method of isoproterenol hydrochloride. The preparation method takes water, N-dimethylformamide or an aqueous solution of the N, N-dimethylformamide as a solvent, takes borohydride as a reducing agent to carry out reduction reaction on the isopropyl adrenalone or the salt thereof, has mild reaction conditions, obviously improves the production safety compared with the conventional hydrogenation reduction process, greatly reduces the production cost, has less borohydride consumption and increases the environmental protection to a certain extent. The product obtained by the preparation method has high purity, is suitable for industrial production of isoproterenol hydrochloride serving as a medicinal raw material product, and can effectively avoid toxic and side effects caused by impurities. |
