Selective solvent extraction for the purification of protected nucleosides |
摘要 |
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.
