Process for the preparation of O-desmethyl-venlafaxine and salts thereof |
| abstract |
The present invention relates to a novel process for the preparation of O-desmethyl venlafaxine (ODV) and the pharmaceutically acceptable salts thereof, wherein it comprises (i) provision of spiro-venlafaxine compound as intermediate; (ii) conversion of spiro-venlafaxine intermediate into ODV free base in a one-pot process; and (iii) optionally conversion ODV free base into pharmaceutically acceptable salts. The present invention further relates to novel processes for the preparation of crystalline salts of ODV-succinate and ODV-oxalate. |
