Title
(EN) AN IMPROVED PROCESS FOR THE PREPARATION OF PYRROLE DERIVATIVES
(FR) PROCÉDÉ AMÉLIORÉ DE PRÉPARATION DE DÉRIVÉS DE PYRROLE
Abstract
(EN)
The present invention relates to an improved process for the preparation of pyrroles derivatives having hypolipidemic and hypocholesteremic activities. In particular, the invention relates to an improved process for the preparation of 2- ethoxy-3-(4-(2-(2-methyl-5-(4-(methylthio)phenyl)-1H-pyrrol-1-yl)ethoxy) phenyl)propanoate and its pharmaceutically acceptable salts, hydrates, solvates, polymorphs or intermediates thereof. The invention also relates to an improved process for the preparation of mesylate compound (A1).
