Preparation of High Specific Activity [15,16-3H]-7-Benzylidenenaltrexone

The preparation of the δ1‐specific ligand 7‐benzylidenenaltrexone (BNTX), labeled with tritium at high specific activity (14.4 Ci/mmol) was prepared in 33% yield and >98% purity by the aldol condensation of high specific activity [15,16‐3H]naltrexone with benzaldehyde at high dilution.
