The parameters of two exchange methods of preparing pure 97% labelled 17-Br-HDA in acetone and in benzene with dry NaI* in a closed system are described. In aprotic solvents the need for a phase transfer catalyst up to 50μg is necessary to dissolve the dry NaI*. The use of aqueous medium in the exchange is totally prohibited. Energies of activation are calculated for both reactions.
