Abstract

The preparation of 21‐diazoprogesterone‐6,7‐^3^H~2~ is described. Progesterone was dehydrogenated with chloranil to give Δ^6^‐dehydroprogesterone. Degradation of the pregnane side‐chain with sodium hypobromite gave the corresponding carboxylic acid. Catalytic reduction with carrier‐free tritium followed by treatment with oxalyl chloride and then diazomethane afforded 21‐diazoprOgesterone‐6,7‐^3^H~2~ with a specific activity of 42 Ci/mmol.
