Blonanserin one kind of crystal form and preparation method

The present invention discloses a color Linxin Jing Tambunan type and preparation method, X- ray diffraction pattern of the crystal 1 shown in FIG. The method of preparing the crystalline form and its related substances can effectively reduce the product, increasing the purity, increased reaction yield. The polymorph of enhanced product stability, especially to facilitate storage under high temperature and high humidity conditions. Further preferred chemistry and its stable crystal arrangement given its excellent solubility, in the preparation of medicament, can achieve satisfactory accuracy of dosage, increasing the safety of the product, to reduce the risk to the patient, and therefore for for the preparation of a stable pharmaceutical formulation.
