Abstract
The synthesis of 2-(2,4-difluorophenyl)-4,5-bis(4-methoxyphenyl)imidazole labelled with carbon-14 in the 2-position of the imidazole ring has been achieved in four stages starting from barium [14C] carbonate via 2,4-difluoro-[carboxyl]14C benzoic acid and the corresponding aldehyde. The overall radiochemical yield was 20% and the product obtained with a radiochemical purity in excess of 99% by the analytical systems used.
