can be crude cabergoline or cabergoline in any form semi solid cabergoline can be prepared by the known procedure disclosed in the literature eur j med chem 24 1989 421 and can be additionally purified by chromatography followed by evaporation of the eluting solvents to obtain amorphous material semi solid or oil or mixture thereof halogenated aromatic solvent can be selected from a group of fluoro difluoro or chloro substituted benzene preferably chloro substituted benzene and toluene preferably chlorobenzene and 2 chlorotoluene most preferably 2 chlorotoluene optionally said halogenated aromatic solvents can be combined with low amounts of a water miscible aprotic solvent such as acetonitrile or acetone as co solvents as an anti solvents aliphatic hydrocarbons such as pentane heptane or hexane c5 c7 alkanes can be used which cause lowering the solubility of cabergoline in abovementioned aromatic solvents with optionally addition of the co solvent at ambient temperatures a process for the preparation of pure cabergoline form l according to the present invention comprises the steps of preparation of semi solid cabergoline via extraction of crude cabergoline first dissolved in the water acetonitrile mixture from said mixture into dichloromethane organic phase and evaporation of organic solvents to obtain semi solid cabergoline dissolving of semi solid cabergoline in aromatic solvent preferably chloroaromatic solvent e g.
