POLYMORPHIC FORMS OF RIMONABANT BASE AND PROCESSES FOR PREPARATION THEREOF

摘要

The present invention provides process for crystalline forms of Rimonabant base, including processes that prepare crystalline forms of Rimonabant base. Also provided is a crystalline Rimonabant base form I having a substantially reduced residual solvent content, including processes that prepare such crystalline Rimonabant form I. These crystalline forms of Rimonabant base may be in a pharmaceutical compositions further comprising at least one pharmaceutically acceptable excipient.
