Fluocinolone acetonide was tritiated by selective reduction of the 1,2-double bond of the O-protected analog under tritium, followed by re-establishment of the 1,2-double bond and deprotection. Protection of both hydroxyl functionalities was required. The product was obtained with specific activity 36.8 Ci/mmol. Copyright © 2009 John Wiley & Sons, Ltd.
