| titleOfInvention | Novel preparation method of brivaracetam |
| abstract | The invention provides a preparation method of brivaracetam, which takes (R) -4-propyl dihydro-2 (3H) -ketone which is purchased from the market as a raw material to synthesize the brivaracetam in four steps under certain conditions. The preparation method provided by the invention can directly obtain the high-optical-purity brivaracetam without adopting a chiral preparation chromatographic column separation step. The method has the advantages of high yield, simple and convenient post-treatment, low production cost and suitability for industrial production. |
