PROCESS FOR PREPARATION OF MONTELUKAST SODIUM

Disclosed is a process for the preparation of montelukast sodium. The process comprises a) reacting 2-(2-(3(S)-(3-(2-(7-chloro-2-quinolinyl)-ethenyl)phenyl)-3-hydroxypropyl)phenyl)-2-propanol with methane sulfonyl chloride and coupling the resultant mesylate compound with l-(mercaptomethyl)cyclopropane acetic acid in presence of a base and free alkali source followed by saltification with an amine in a single step reaction and b) converting the montelukast amine salt to montelukast sodium salt.

AN IMPROVED PROCESS FOR PREPARING MONTELUKAST AND SALTS THEREOF

A method for the preparation of montelukast and salts thereof has been described. The method comprises of following steps: (a) (S)-1-(3-((E)-2-(7-chloroquinolin-2-yl)vinyl)phenyl)-3-(2-isopropenylphenyljpropyl methane sulphonate (styrene mesylate salt) (b) coupling with 1-(mercapto methyl) cyclopropane acetic acid followed by salification with an amine gives styrene amine salt (c) Converting styrene amine salt to Montelukast amine salt (d) Converting Montelukast amine salt to Montelukast free acid and or its required alkali/alkaline salt.
