    摘要: The present invention discloses a method for preparing cabergoline form I by combining cabergoline and a solvent comprising ethylbenzene to form a solvate and obtaining form I from the solvate. Also disclosed in a method for preparing cabergoline form I by combining cabergoline and a first solvent to form a solution and additionally including a second solvent to the solution, followed by crystallization to form cabergoline form I. Further disclosed is a solvate form of cabergoline comprising cabergoline and ethylbenzene and, optionally, n-heptane.
