| titleOfInvention | Preparation method for rivastigmine intermediate |
| abstract | The invention relates to a preparation method for a rivastigmine intermediate, specifically to a preparation method with high stereoselectivity for 3-((S)-1-((S)-1-phenylethylamino)ethyl)phenyl ethyl (methyl) carbamate. With the method provided by the invention, industrial large-scale production of 3-((S)-1-((S)-1-phenylethylamino)ethyl)phenyl ethyl (methyl) carbamate is more easier to operate and needs less cost, and a product has high purity. Reduction in cost for and improvement of purity of 3-((S)-1-((S)-1-phenylethylamino)ethyl)phenyl ethyl (methyl) carbamate, an important intermediate for synthesis of rivastigmine, enable synthetic cost for rivastigmine to be substantially reduced and purity of rivastigmine to be improved. |
