Abstract
An improved method for preparation of cocaine receptor binding ligands is provided. The method calls for the preparation of the silylaryl intermediate prepared from phenyl trimethylsilane and a anhydroecgonine methyl ester appropriately substituted. The intermediate is prepared in high purity and can be directly converted to the binding ligand by iodine substitution.
