To prepare 2,6-dimethyl-4-nitro-3-chloropyridine, there are various methods. First, it can be obtained from suitable pyridine derivatives through nitration, chlorination, methylation, etc. First, take the pyridine derivative, use a nitrifying agent, and under appropriate conditions, make the nitro group enter the specific position of the pyridine ring to obtain the nitropyridine derivative.
