5) The title product [3H]- or [2H]-labeled at C7 of the steroid nucleus is synthesized starting from 21-acetoxy-11beta,17alpha-dihydroxy-6-methylpregna-4,6-diene-3,20-dione (XII), which is hydrogenated with tritium or deuterium over Pd/C in methanol yielding a mixture of the two isomeric dihydro compounds (XIII) and (XIV). The treatment of this mixture with 6N HCl affords compound (XV) labeled at C7, which is dehydrogenated with SeO2 in refluxing tert-butanol and deacetylated with KOH in methanol, yielding methylprednisolone labeled with 3H or 2H at C7 (XVI). Finally, this compound is condensed with 8-oxo-8-[N-(2-sulfoethyl)-N-methylamino]octanoic acid (III) by means of tert-butoxycarbonyl chloride as before.
