Claim 5:
6. A method for preparing a radiolabeled compound targeting prostate specific membrane antigen, wherein the method comprises the following steps: dissolving the compound shown in Formula (II-1) according to claim 1 in a buffer solution or deionized water; and adding a radionuclide solution to a resulting solution for a reaction under closed conditions for 5-40 min to produce a radionuclide labeled complex;
or the method comprises the following steps: dissolving an appropriate amount of the compound shown in Formula (II-1) according to claim 1 in a buffer solution or deionized water; treating the obtained solution to aseptic filtration, followed by loading into a container, freeze-drying and sealing with a stopper to obtain a freeze-dried medicine box; and then adding an appropriate amount of an acetic acid solution or a buffer solution to the freeze-dried medicine box for dissolution, and adding a corresponding radionuclide solution for a reaction under closed conditions for 5-40 min to produce a radionuclide labeled complex.
