Medicament intermediate and preparation method of fluroxypyr 1-methylheptyl ester

The invention discloses a medicament intermediate and a preparation method of fluroxypyr 1-methylheptyl ester, and relates to the field of organic synthesis. The preparation method of the medicament intermediate has the advantages that a molecular sieve is added, a fluoridation reaction and next amination reaction of pentachloropyridine can be realized through one-pot reaction, complex separation steps are saved, product loss caused by the separation process is avoided, and the key medicament intermediate for preparing herbicide can be prepared at high yield. The preparation method is easy to operate, is low in equipment demand, contributes to lowering production cost, and is suitable for large-scale industrial production. The preparation method is characterized in that low-cost and readily-available pentachloropyridine is taken as an initial raw material, the fluoridation reaction and next amination reaction are implemented by adopting the one-pot method to obtain key medicament intermediate; on the basis of the medicament intermediate, a hydroxylation reaction and a condensation reaction are implemented to obtain efficient high-yield fluroxypyr 1-methylheptyl ester. The preparation method is reasonable in route design, is simple in steps, is convenient to operate, is low in cost, is low in pollution, and is suitable for industrial large-scale production.
