Method for making cocaine receptor binding ligands and intermediates therefor
An improved method for preparation of cocaine receptor bindingligands is provided. The method calls for the preparation of thesilylaryl intermediate prepared from phenyl trimethylsilane and aanhydroecgonine methyl ester appropriately substituted.
