SULPHONATE PRECURSOR HAVING A 1,2,3-TRIAZOLIUM SALT, A PRODUCTION METHOD THEREFOR AND AN INTRAMOLECULAR NUCLEOPHILIC FLUORINATION REACTION USING THE SAME

摘要

The present invention relates to a sulphonate precursor having a 1,2,3-triazolium salt, and to a production method and use therefor, and more specifically exhibits the advantages that the reaction rate can be increased by introducing an organic salt having a phase-transfer catalyst effect into the leaving group of the precursor and thereby inducing an intramolecular nucleophilic substitution reaction of the nucleophile and sulphonate precursor, and use of a separate phase-transfer catalyst is avoided. The invention can be used as a sulphonate precursor for the effective production of an [18F]radiopharmaceutical used in positron emission tomography.
