PROCESSES FOR THE PREPARATION AND PURIFICATION OF PALIPERIDONE PALMITATE

摘要

The present invention encompasses processes for the preparation and purification of paliperidone palmitate, for the purification of palmitic acid, for the preparation of paliperidone sodium salt and the preparation of paliperidone tetradecanoate or octadecanoate ester. The latter may further be used in a quantification method for determining the purity of paliperidone palmitate.
