Method for producing 4-borono-L-phenylalanine having 18F atom introduced thereinto, and precursor of 4-borono-L-phenylalanine having 18F atom introduced thereinto

摘要

¹⁸F-labeled 4-boronophenylalanine (BPA) can be produced by preparing and further processing a precursor of ¹⁸F-labeled BPA represented by the following formula:; in which 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).
