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.

best activity. In particular, ortho substitution of the benzyl group with an acidic function was crucial for maximum potency. In cases similar to 32, where the benzyl group possesses an ortho carboxylate, the N-2-substituted tetrazole isomer showed 100-fold greater activity relative to the corresponding N-1 isomer. This pattern was reversed when the acid was substituted at the para position. The quinoline
