Application In Synthesis of 3,5-Dimethyl-1H-pyrazole<\/a>.

Based on the agrochemical structure of anthranilic diamides, fourteen novel N-substittitedphenyl-2-pyrazolylnicotinamides were conveniently synthesized with 2-chloro-3-cyanopyridine and 4-bromopyrazole or 3,5-dimethylpyrazole as starting materials, via an acyl transposing design strategy. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay tests indicated that most of these compounds exhibited obvious insecticidal activity at the test concentration of 200 mg\/L, among which N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)-2-(3,5-dimethyl-1H-pyrazol-1-yl)nicotinamide (II) possessed a 70% mortality rate against Mythimna separata Walker: some of the compounds displayed favorable fungicidal activities at 50 mg\/L towards Physalospora piricola and Alternaria solani Sorauer, especially 2-(4-bromo-1H-pyrazol-1-yl)-N-(2-(cyclopropylcarbamoyl)-4-iodo-6-methylphenyl)nicotinamide (If) and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)nicotinamide (Ih) against Physalospora piricola, and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(propylcarbamoyl)phenyl)nicotinamide (Id) against Alternaria solani Sorauer had growth inhibitory rates of 62.9%, 54.3% and 54.5%, respectively. These research results provide important reference for the further study of novel 2-pyrazolylnicotinamide derivatives.<\/p>\n
