Abstract: | 6-benzylaminopurine-[p-1H-benzyl] at a specific activity of 10 Ci/mmol was synthesized by reacting p-bromo-6-benzylaminopurine with carrier-free tritium gas in the presence of 10% Pd/C. A radiochemical purity of 97% was obtained by a one-step purification of the tritiated reaction product using cellulose TLC. This simple procedure yields the highly active cytokinin, 6-benzylaminopurine, with tritium at near maximum specific activity in a known, stable position. |
