-
Paragraph 0042; 0046, (2017/11/08)
The invention discloses a preparation method of salmeterol. The method includes the following steps: carrying out a condensation reaction on a compound 2 and a compound 3 under an alkaline condition to obtain an intermediate 4; carrying out acidic hydrolysis to obtain an intermediate 5, and reducing the intermediate 5 to obtain an intermediate 6; and removing a benzyl group from the intermediate 6 by using palladium on carbon (Pd/C) to obtain a salmeterol base. The preparation method has the advantages of mild reaction conditions, simple post-treatment, low cost, high yield high product purity, and easiness in realization of industrialization.
