| titleOfInvention | A kind of synthetic method of florfenicol intermediate |
| abstract | The present invention relates to a method for synthesizing a florfenicol intermediate (IV), which specifically comprises the following steps: dissolving compound (II) in an organic solvent, and performing mesylation under basic conditions to obtain compound (III) ); compound (III) is ring-closed under the action of a base to obtain compound (IV); compound (IV) undergoes fluorination and ring-opening to obtain florfenicol intermediate (I). The method of the invention has novel design, mild conditions, simple and convenient operation, and is suitable for industrial production. |
