Title
(EN) SELECTIVE SOLVENT EXTRACTION FOR THE PURIFICATION OF PROTECTED NUCLEOSIDES
(FR) EXTRACTION SELECTIVE PAR SOLVANT UTILISEE POUR PURIFIER DES NUCLEOSIDES PROTEGES
Abstract
(EN)
A process for the purification of nucleosides, and more particularly to a selective solvent extraction method for purifying protected nucleosides. In the purification process, solid particles of protected nucleosides are selectively washed to remove undesirable polar and/or non-polar impurities, while leaving the solid particles substantially undissolved.
(FR)
L'invention porte sur un procédé de purification de nucléosides et plus particulièrement sur un procédé d'extraction sélective par solvant permettant de purifier des nucléosides protégés. Dans le procédé de purification, des particules solides de nucléosides protégés sont sélectivement lavées pour éliminer les impuretés polaires et/ou non polaires indésirables, sans que lesdites particules solides soient sensiblement dissoutes.
