| titleOfInvention | Preparation and refining method of alpha-(N-benzyl-N-methyl amino)-m-hydroxyacetophenone hydrochloride |
| abstract | The invention relates to preparation and a refining method of alpha-(N-benzyl-N-methyl amino)-m-hydroxyacetophenone hydrochloride. The alpha-(N-benzyl-N-methyl amino)-m-hydroxyacetophenone hydrochloride is prepared by performing catalytic bromination, amination condensation and a salifying reaction on m-hydroxyacetophenone, a bromizating agent and methyl benzyl amine which serve as main raw materials and single petroleum ether which serves as a solvent. The method has a simple and convenient process, uses readily available raw materials and avoids using chemical solvents such as inflammable solvents, explosive solvents, toxic solvents and the like in a preparation process. The alpha-(N-benzyl-N-methyl amino)-m-hydroxyacetophenone hydrochloride has the characteristics of high yield, high purity, low cost, environmental friendliness and the like. |
