A synthesis method for preparing Montelukast sodium intermediate 2-(2-(3-(2-(7-chloro-2-quinolyl)vinyl)phenyl-3-oxopropyl)phenyl) propanol is provided. In this method, the target compound is prepared by condensing the starting materials 7-chloroquinaldine and 3-cyanobenzaldehyde, and then reacting the resultant product with 2-(2-ortho-(2-haloethyl)-phenylpropyl)tetrahydropyrane ether. The present invention can easily obtain start materials and is applicable for mass production.
