Abstract:
Provided are a crystalline form A of 2-[(2R)-2-methyl-2-pyrrolidyl]-1H-benzimidazole-7-carboxamide dihydrochloride and the preparation method and use thereof. The X-ray powder diffraction pattern of crystalline form A shows characteristic peaks at 2theta values of 8.3°±0.2°, 26.7°±0.2°, 16.1°±0.2°. Crystalline form A, compared with the existing crystalline forms, has a surprisingly excellent solubility, mechanical and storage stabilities and particle size distribution, is a more ideal crystalline fotbnn compared with the prior art forms, better satisfies medicinal requirements, and plays an important role in future optimization and development of the drug.

Claim (Index 6):
The preparation method according to  claim 5 , wherein said alcohol is ethanol or isopropanol, and said ketone is acetone or methyl isobutyl ketone, and said ester is ethyl acetate or isopropyl acetate, and said nitrile is acetonitrile.
