Abstract

Mepindolol, a potent ß‐adrenoceptor blocking agent, was labelled with ^14^C by two different routes yielding the 2‐[^14^C]methyl and [2‐^14^C] products. While the first alternative was abandoned because of low overall yield, the latter route provided mepindolol with a specific activity of 2.06 GBq/mmole (55.8 mCi/mmole) and in a radiochemical yield of 40% starting from Ba^14^CO~3~.
