Abstract
A novel crystalline polymorphic form of ulipristal acetate useful as an agent for preventing and/or treating uterine leiomyoma and as a contraceptive, and a process for producing the crystalline polymorphic form are provided. The novel crystalline polymorphic form of ulipristal acetate is obtained by dissolving an isopropanol-solvated crystal of ulipristal acetate in a mixed solvent containing ethanol and water, and crystallizing an ulipristal acetate from the solution without addition of a seed crystal to the solution.
