Donepezil polycrystals and process for producing the same |
| abstract |
Novel polycrystals (A) to (C) ofndonepezil that serves as a precursor fornproducing donepezil hydrochloride havingnexcellent pharmaceutical effects and beingnexcellent in handleability and remarkablynreduced in residual solvent; and in industrialnprocess for producing the same. Thenpolycrystals are characterized by the powder X-rayndiffraction pattern and/or infrarednabsorption peaks of donepezil represented bynchemical formula (I). |
