| titleOfInvention | A process for the manufacture of zonisamide |
| abstract | The present invention describes an improved process for the preparation of 1,2Benzisoxazole-3-methanesulphonamide (Zonisamide), a well known anti-epileptic agent which possesses anti-convulsant and anti-neurotoxic effects. Other aspect of this invention are isolation of a key intermediate, viz., crystalline sodium chloride associated 1,2Benzisoxazole-3-methane sodium sulfonate (BOS-Na:NaCl). The isolated crude BOSNa:NaCl is directly converted to Zonisamide using controlled molar ratio of chlorosulfonic acid to avoid the disulfonated side products. The analytical characteristics like IR and XRD data of the BOS-Na:NaCl are also reported to confirm its nature. |
