A convenient synthetic pathway for 14C labeling of fentanyl [N-(1-phenethyl-4-piperidinyl)- propionanilide], a widely used narcotic analgesic agent, with good radiochemical yield was developed.
Synthesis of 2-(methylsulfonyl)-5-(4-(methylsulfonyl) phenyl)-4-phenyl-1H-[5-<sup>14</sup>C]imidazole, a selective COX-2 inhibitor, via asymmetrical benzoins
4,5-Diarylimidazoles labeled with carbon-14 in the 5-position of the imidazole ring were prepared as a part of three-step sequence from 2-hydroxy-1-(4-(methylthio)phenyl)-2-phenyl[1-(14) C]ethanone as a key synthetic intermediate which has been synthesized from potassium [(14) C]cyanide.
