Method for producing 4-borono-L-phenylalanine having 18F atoms introduced and precursor of 4-borono-L-phenylalanine having 18F atoms introduced

摘要

The purpose of the present invention is to provide: a novel method for producing 18 F-labeled 4-boronophenylalanine (BPA) ; and a precursor of 18 F-labeled BPA. 18 F-labeled BPA can be produced by preparing a compound represented by formula (1) and using the compound. In the formula, R1 represents a bromo group, an iodo group, a fluoro group, a diazaborinane derivative, BX3- or BX3-M+ (wherein X represents a halogen atom; and M+ represents a monovalent monoatomic cation, a polyatomic cation or a complex cation).
