The Uses of Ethyl 4-fluorobenzoate
Ethyl 4-fluorobenzoate may be used in the synthesis of 4,4′-(1,4-piperazinediyl) bisbenzoic acid ethyl ester.
General Description
Ethyl 4-fluorobenzoate is a clear colorless liquid. The purified [18F]fluoride is used for solution phase nucleophilic labeling of ethyl [18F]4-fluorobenzoate. Ethyl 4-fluorobenzoate causes N-arylation of 5-methoxyindole in presence of 18-crown-6 by using microwave-assisted technology.
