摘要:
A process for producing crystalline form I of cabergoline, which process comprises the preparation of Form V using heptane as precipitation solvent, and its exclusive conversion into crystalline Form I of cabergoline. The present crystallization process from toluene-heptane solvent system for form V involves 'reverse addition' of toluene-cabergoline concentrate to cold heptane.
