## Abstract A new convenient method for the preparation of the title compound is described. The method consists of selective tritiation of betamethasone 17‐benzoate (9α‐fluoro‐11Ξ²,17,21‐trihydroxy‐16β‐methyl‐1,4‐pregnadiene‐3,20‐dione 17‐benzoate) (1) with the use of tris(triphenylphosphine)rhodium

Betaniethasone 21 -acetate was catalytically reduced with tritium. The crude product was oxidized with 2,3-dichloro-5,6-dicyano-1,4benzoquinone ( D D Q ) to betamethasone-I,2,4JH 21-acetate. Hydrolysis gave bet~methasone-1,2,4-~H, which, when allowed to react with trimethylorthobenzoate, gave both b
