Abstract
This invention discloses method for preparing a non-radioactive standard β-CFT. Using cocaine hydrochloride as the starting material, and after a series of hydrolysis, dehydration, esterification and bonding reactions, a non-radioactive standard (2β-Carbomethoxy-3β-(4-fluoropenyl) tropane) is prepared. Furthermore, this preparation method has fewer steps, is easy to operate, and the purity of the product is as high as 97.97%. Therefore, the method for preparing a non-radioactive standard β-CFT can promote the development of positron imaging in the diagnosis of Parkinson's disease.
