A process for the separation of moprolol having formula (I) into its two optical antipodes, by salifying racemic moprolol with L(+)glutamic acid; treating the thus obtained mixture of diastereoisomeric salts with a water/alcohol mixture, in this way separating the L(+)glutamate insoluble salt of (+)moprolol; treating the resultant mother liquors which contain in solution the L(+)glutamate sart of (-)moprolol with a base so as to separate the levorotatory isomer of crystalline moprolol, which finally undergoes a purification. …<??>Also a pharmaceutical composition containing said levorotatory isomer of …<CHEM>… |
