- Preparation method for benflumetol and matched system thereof
-
The invention belongs to the field of benflumetol, and relates to preparation and a system for the benflumetol, in particular to a preparation method for the benflumetol and a matched system thereof.The preparation method for the benflumetol is completed by sequentially through bulk drugs, a plurality of intermediates and the benflumetol. The matched system for the preparation method sequentiallycomprises an intermediate I matched system, an intermediate II matched system, an intermediate IV matched system, an intermediate V matched system and a benflumetol matched system. According to the invention, overall preparation is simple, reasonable and highly-efficient; the required time is greatly shortened; and exploration of industrial production conditions of the benflumetol is completed.
