## Abstract Tritium‐labeled budesonide was prepared by the selective reduction of a double bond in the butenylenedioxy side chain using carrier‐free tritium and palladium on carbon as a catalyst in absolute ethanol. Although the reduction gave a mixture of the desired product and the expected bypro
