Abstract
Novel crystalline polymorphic Form III of rimonabant and an amorphous form of rimonabant. Crystalline form III of rimonabant is prepared by dissolving rimonabant in an aprotic polar solvent such as acetonitrile or tetrahydrofuran, pouring the solution into water and stirring the resulting mixture. Amorphous form of rimonabant is prepared by dissolving in and alcohol of formula ROH, wherein R is an alkyl, such as methanol or isopropyl alcohol, and stirring the mixture. Rimonabant of formula (I) is obtained in such a way that an ester of 5-(4-chlorophenyl)-l-(2,4-dichlorophenyl)-4-methyl-lH-pyrazole-3-carboxylic acid of formula (III), wherein R is a Cl-C5 alkyl group, phenyl group or a substituted phenyl group, preferably methyl or ethyl, is reacted, in a solvent, preferably in a solvent from the group of diethyl ether, tetrahydrofuran, dioxan, dichloromethane, acetonitrile, toluene or their mixtures, or in an excess of N-aminopiperidine, with N-aminopiperidine with catalysis by at least one Lewis acid at a temperature from 0° C to the boiling point of the solvent or mixture of solvents used. Pharmaceutical compositions containing the above forms and use of the above forms for the manufacture of a medicament the treatment of obesity, for curing of the habit of smoking or for the treatment of Alzheimer or Parkinson diseases are also described.
