Tritium Labeling of 7-Isopropoxyisoflavone

Catalytic tritiodehalogenation of 8-bromoipriflavone and 6,8-dibromoipriflavone resulted in [8-3H]ipriflavone (3) and [6,8-3H2]ipriflavone (7) with specific activities of 1.08 TBq/mmol (29.2 Ci/mmol) and 1.94 TBq/mmol (52.4 Ci/mmol), respectively. 8-Bromoipriflavone was synthesized by direct bromination of ipriflavone, while 6,8-dibromoipriflavone was formed by isopropylation of the phenolic OH group of 6,8-dibromo-7-hydroxyisoflavone which itself was prepared from 7-hydroxyisoflavone and elemental bromine.
