Abstract
The present invention provides a novel crystalline form I of hydrochloride, a crystalline form II of hydrochloride, a crystalline form of succinate, a crystalline form of tartrate, a crystalline form I of fumarate and a crystalline form II of fumarate of 1-(5-(2,4-difluorophenyl)-1-((3-fluorophenyl)sulfonyl)-4-methoxy-1H-pyrrol-3-yl)-N-methylmethanamine. The above-described novel crystalline forms have high solubility in water and excellent stability under moisture-proof conditions and high-humidity exposure conditions, and thus can be pharmaceutically used.
