PROCESS FOR THE PREPARATION OF CRYSTAL FORMS OF CABERGOLINE VIA NOVEL STABLE SOLVATES OF CABERGOLINE

摘要

The present invention relates to a process for producing cabergoline crystal forms. The process comprises preparation of the desired solvate of cabergoline from a solution of cabergoline in chloroaromatic solvents. Afterwards cabergoline crystal form is prepared by recovery from a solvate of cabergoline by drying or with desolvating in a solvent media.
