-
, (2021/06/26)
The invention discloses a synthesis method of a 2-fluoro-3-nitrobenzoic acid intermediate raw material. The invention provides a novel synthesis route, and an important medical intermediate can be rapidly and conveniently prepared from cheap and easily available raw materials. The process method comprises the following steps: starting from o-methylphenol, carrying out nitration reaction to selectively generate a key intermediate 2-methyl-6-nitrophenol, carrying out hydroxyl chlorination to generate 2-chloro-3-nitrotoluene, then carrying out fluorination reaction to generate 2-fluoro-3-nitrotoluene, and finally oxidizing methyl under the action of an oxidant to generate 2-fluoro-3-nitrobenzoic acid. The method is not only high in yield, but also suitable for large-scale production.
