CRISTALLINE ( - ) - 3R,4R -TRANS-7-METHOXY -2,2-DIMETHYL-3-PHENYL-4- {4-[2-(PYRROLIDIN-1-YL)ETHOXY] PHENYL}CHROMANE, HYDROGEN MALEATE

摘要

The present invention provides novel crystalline ( - ) - 3R,4R -trans-7-methoxy -2,2-dimethyl-3-phenyl-4- {4-[2-(pyrrolidin-1-yl)ethoxyl] phenyl}chromane, hydrogen maleate useful for reducing or preventin bone loss as well as pharmaceutical compositions containing the same. A process for preparing ( - ) - 3R,4R -trans-7-methoxy-2,2-dimethyl-3-phenyl-4-{4-[2-(pyrrolidin-1-yl)ethoxy]phenyl}chromane, hydrogen maleate is described.
