Synthesis of 2-(methylsulfonyl)-5-(4-(methylsulfonyl) phenyl)-4-phenyl-1H-[5-(14)C]imidazole, a selective COX-2 inhibitor, via asymmetrical benzoins. | LitMetric

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.
