Preparation Method:
Methyl can be prepared by the following steps:
1. First, p-nitrobenzene boronic acid reacts with methyl iodide under appropriate reaction conditions to obtain methyl p-nitrobenzene.
2. Then, under alkaline conditions, methyl p-nitrobenzene reacts with tribromomethane to generate methyl 5-bromo-2-methyl-3-nitrobenzoate.
3. Finally, in the presence of a fluorinating reagent, methyl 5-bromo-2-methyl-3-nitrobenzoate is subjected to a fluorination reaction to obtain the target product Metyl.
