Crystalline aripiprazole Type II can be formed without solid state heat treatment. Instead a liquid is used such as in crystallizing from a solvent, especially 2-propanol, dimethyl sulfoxide, tetrahydrofuran or a combination thereof, or in a solvent mediated solid-solid transformation, typically in ethyl acetate.
L'aripiprazole de type II cristallin selon l~invention peut être formé sans traitement thermique à l~état solide. Au lieu de cela un liquide est utilisé pour une cristallisation dans un solvant, plus particulièrement le 2-propanol, le diméthylsulfoxyde, le tétrahydrofuranne ou une combinaison de ceux-ci, ou dans une transformation de solide en solide par l~intermédiaire d~un solvant, typiquement dans l~acétate d~éthyle.
