Two series of benzoylphenylurea derivatives were synthesized as candidate propesticides by a nucleophilic addition reaction between 2,6-difluronbenzoyl isocyanate and N-substitutedaniline. The new compounds were identified by 1H NMR spectroscopy, electron ionization-mass spectrometry, and elemental analyses. The bioactivities of the new

The authentic standard 2,6-difluoro-N-(3-methoxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide was synthesized from 2,6-difluorobenzoic acid and 3-amino-5-hydroxypyrazole in 9 steps with 1% overall chemical yield. Direct desmethylation of the reference standard with TMSCl/NaI gave the precursor 2,6-difluoro-N-(3-hydroxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide for radiolabeling in 70% yield. The target tracer 2,6-difluoro-N-(3-[(11)C]methoxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide
