Versuchsvorschrift
The oil obtained by purification on a chromatographic column after the final step of the synthetic path according to the preparation described in Eur. J. Med. Chem., 24, 421, (1989) and containing 100 g of pure cabergoline was dissolved in toluene to give 243 g of a cabergoline toluene solution. The solution was introduced into a reactor pre-cooled at −12[deg.] C., and 182 g of toluene were added to give a 23.5%. w/w cabergoline concentration in this solvent. After cooling again at −12[deg.] C., 362 ml of diethyl ether were added. The mixture was cooled again at −12[deg.] C. and stirred at this temperature for about 17 hours. The obtained precipitate was filtered under vacuum and smoothly dried. The resultant crystal solvate form V was identified by XRD, DSC, IR and NMR, data shown in FIGS. 5-8 respectively.
