A kind of preparation method of tapentadol intermediate m-methoxypropiophenone |
| abstract |
The invention provides a method for preparing tapentadol intermediate m-methoxypropiophenone. The method uses m-hydroxybenzoic acid as a starting material to obtain the target product m-methoxypropiophenone through methylation, condensation, hydrolysis and decarboxylation reactions. Propiophenone. The reaction route section of the invention has simple process and high yield up to 95%, which creates good conditions for industrial scale production and commercialization of products. |
