Definitions
- the present invention relates to a method for producing a compound labeled with 18 F and a polymer compound used in the production method.
- the 18 F nuclide Since the 18 F nuclide has a half-life of about 2 hours, a rapid and simple production method is required.
- the target product can be purified quickly and easily.
- the reactivity is improved by including both the label precursor compound and the crown ether in the polymer compound, a more efficient 18 F-labeled compound can be produced.
- the compound labeled with 18 F is produced, for example, by the following liquid phase synthesis method or solid phase synthesis method.
- Liquid-phase synthesis method A labeled precursor compound (compound to be labeled) is reacted with a small amount of 18 F ions. Therefore, since the product contains an excess of unreacted label precursor compound, much effort is required for purification of the target compound. Further, in order to overcome the low reactivity of fluoride ions, a highly reactive label precursor compound, that is, a label precursor compound with low stability is often used.
- Solid phase synthesis method By using a labeled precursor compound immobilized on a solid phase, only the reaction product is cut into a solution, thereby facilitating separation of the unreacted product and the reaction product (Patent Document 1, Patent Document 2, Non-Patent Document 1). This method was expected to be an effective technique for facilitating the purification of compounds.
- the reactivity of the labeled precursor compound immobilized on the solid phase generally decreases.
- the volumetric efficiency decreases and the amount of solvent required increases, so it is difficult to keep the fluoride ion concentration high. Therefore, although the purity of the obtained compound is high, it is difficult to obtain a sufficient amount of product.
- Such problems of solid-phase synthesis are also pointed out in Romain Bejot et al., Angew. Chem. 3 lines).
- the present invention is a means for solving the problems of the conventional method for producing 18 F-labeled compound, that is, the problem of purification of the compound in the liquid phase synthesis method and the problem of insufficient yield due to the decrease in reactivity in the solid phase synthesis method Is intended to provide.
- the immobilized labeled precursor compound and fluoride ion are reacted in the presence of crown ether (phase transfer catalyst) (for example, Example 2 (vi) of Patent Document 1). And Example 22 of Patent Document 2).
- crown ether phase transfer catalyst
- the present inventor has found that the reactivity of the labeled precursor compound and fluoride ions is remarkably improved by fixing the crown ether together with the labeled precursor compound on the polymer compound.
- the crown ether immobilized on the polymer compound is generally expected to be less reactive as a catalyst than the free crown ether. Therefore, it was completely unpredictable at the time of filing the present application that the reactivity of the label precursor compound and fluoride ions is improved by fixing the crown ether on the polymer compound.
- the present invention has been completed based on the above findings.

- the labeling precursor compound is represented by the following formula (A) or (B)

- the present invention has the following effects, for example. 1) Since only the labeled compound is cut out from the polymer compound, separation and purification of the labeled compound, the labeled precursor compound and the phase transfer catalyst are easy. 2) Since a polymer compound is constructed from a labeled precursor compound and a phase transfer catalyst, the volumetric efficiency is similar to that when a labeled precursor compound soluble in a conventional solvent is used. 3) Reactivity is higher than when the reaction is performed using a labeled precursor compound soluble in a normal solvent. Therefore, efficient fluorination becomes possible using a label precursor compound that is more stable than the conventional one.
