Preparation of pure citalopram |
| abstract |
The present invention relates to an industrially advantageous method for the purification of Citalopram (Formula I) wherein desmethyl citalopram (Formula II), present in crude Citalopram as an impurity, is methylated to produce pure Citalopram. The resulting Citalopram product is isolated as the base or a pharmaceutically acceptable salt thereof |
