Synthesis technology of bisoprolol

The invention relates to a synthesis technology of bisoprolol. The technical scheme of the technology comprises the following steps: (1) using 4-hydroxybenzyl alcohol and isopropoxyethanol to perform the etherification reaction, using strongly acidic styrene type cation exchange resin as catalyst to ensure the alcoholic hydroxyl group etherification reaction to perform under the conditions of room temperature and no solvent; (2) adding sodium hydroxide and epoxychloropropane in the reaction product in the step (1) to ensure phenolic hydroxyl group to perform the etherification reaction; and (3) adding the reaction product in the step (2) in isopropamide, reacting by using boron hydride as catalyst, and preparing bisoprolol. By using the synthesis technology of the invention, the alcoholic hydroxyl group etherification reaction can be performed under the conditions of room temperature and no solvent, the processes of extraction, washing and reduced pressure distillation are simplified; boron hydride is used as catalyst to ensure the amination reaction to perform under a low temperature; the overall yield is increased to above 50%; and the synthesis technology is suitable for industrial production. The solvent used by the technology of the invention can be recycled through distillation; resinic solid acid catalyst can be recycled; and yield and product purity are high.
