Abstract
2-chloro-4-(4-methyl phenylsulfonylamino) pyrimidine was synthesized by reacting 4-toluenesulfonamide with 2,4-dichloropyrimidine at the presence of sodium hydride,using N,N-dimethylacetamide as solvent.Then 2-chloro-4-(4-methyl phenylsulfonylamino) pyrimidine reacted with sodium methoxide,and 2-methoxy-4-(4-methyl phenylsulfonylamino) pyrimidine was prepared.They were confirmed by 1H-NMR and elementary analysis.The herbicidal activities of these two compounds were examined.The biological test results showed that 2-chloro-4-(4-methyl phenylsulfonylamino) pyrimidine had good activities against Brassica napus at the concentration of 100 μg/ml.
