Tritium-labeled [1,2-3H]ethylamine hydrochloride was prepared through a multiple-step sequence in high radioactive specificity. The labeled amine was isolated in high purity following cartridge filtration and used subsequently in the synthesis of [N-ethyl-1,2-3H]apadenoson, an adenosine A2a receptor agonist. The overall yield for this transformation was 56% and the radiochemical purity of the final product was greater than 99%. Copyright © 2008 John Wiley & Sons, Ltd.
