Synthesis of N, N-diethyl-4-[phenyl-(piperidin-4-ylidene)methyl]- [carboxy-14C]benzamide, a potent δ opioid receptor agonist
Gawell, Lars
, p. 131 - 138 (2003)
The synthesis of carbon-14 labelled N,N-diethyl-4-[phenyl-(piperidin-4-ylidene)methyl]-benzamide is described. The radioisotope is introduced via an aryllithium reaction with 14CO2 to form the labelled acid, which is subsequently tra
