Synthese de [14 C] ‐ sulfometuron methyle et de [14 C] ‐ metsulfuron methyle

Abstract
[[2‐14C] pyridimyl] sulfometuron methyl and [2‐14C) ‐ triazinyl] metsulfuron methyl, two sulfonylurea herbicides has been prepared by multistep synthesis. [2‐14C] 2‐amino‐4,6 dimethyl pyrimidine was obtained by two steps from [14C] guanidine and [2‐14C] 2‐amino‐4 methoxy‐4 methyl 1,3,5 triazine was obtained from [14C] cyanamide. The two herbicides were prepared by condensation of heterocycle with methyl‐2 (sulfonylisocyanate) benzoate.
