A process is provided for producing [18F]FACBC, which can reduce the production amount of impurities. Disclosed is a process for producing a radioactive fluorine-labeled organic compound, including a deesterification step of retaining, in a reverse-phase column, a compound represented by Formula (1): wherein R1 is a linear or branched C1-C10-alkyl chain or an aromatic substituent, and R2 is a protecting group; charging the column with an alkaline solution to deesterify the compound, and subsequently discharging the alkaline solution from the column to obtain a compound represented by Formula (2): wherein X is sodium or potassium; and a deprotection step of deprotecting the amino-protecting group of the compound obtained in the deesterification step to obtain a compound represented by Formula (3):
