Abstract
Reacting [.sup.* X]X- with YVaraU in the presence of a cuprous ion catalyst under anaerobic and reducing conditions produces [.sup.* X]XVaraU, where .sup.* X is a radioactive halogen, Y is a second halogen, X and Y are different halogens, and XVaraU is 1-(.beta.-D-arabinofuranosyl)-5(E)-(2-halogenovinyl) uracil, the halogen of which is X. The reaction produces an effective administrable form of [.sup.* X]XVaraU for use in diagnosis and treatment of herpes virus infections.
