Donepezil polycrystals and process for producing the same |
| abstract |
Novel polycrystals (A) to (C) of donepezil that serves as a precursor for producing donepezil hydrochloride having excellent pharmaceutical effects and being excellent in handleability and remarkably reduced in residual solvent; and in industrial process for producing the same. The polycrystals are characterized by the powder X-ray diffraction pattern and/or infrared absorption peaks of donepezil represented by chemical formula (I). <IMAGE> |
