Paragraph 0023; 0024; 0028-0030; 0034-0036, (2017/01/17)
The invention relates to a preparation method of terbutaline sulphate. The technical problems that according to an existing preparation method of terbutaline sulphate, high-pressure hydrogenation and other high-risk operations, and lithium methide, azomethane and other high-risk reagents exist, and cost is high are solved through the preparation method. 3,5-resacetophenone serves as a raw material, and terbutaline sulphate is obtained through hydroxyl protection, the bromination reaction, carbonyl reduction, the condensation reaction and sulphating. The preparation method can be suitable for industrially-produced terbutaline sulphate.
