## Abstract The syntheses of dexamethasone‐16α‐(methyl)‐^14^C and dexamethasone‐16β‐^3^H are described. Tritium labeling was achieved by catalytic addition of tritium to 3‐acetoxypregn‐16‐ene‐11,20‐dione, followed by bromination and dehydrobromination to give 3α‐acetoxy‐16‐^3^H‐pregn‐16‐ene‐11, 20‐
