Synthesis and characterization of the polymorphic form III of 4 - (2 - (4,4 - dimethyl - 2 - 3 - oxooxazolidin - il) thiazol-4-yl) benzonitrile

摘要

Referring to a Crystalline form of 4 - (2 - (4,4 - dimethyl - 2 - 3 - oxooxazolidin - il) thiazol-4-yl) benzonitrile which comprises a Peak of 12.87 at an angle 2 Theta (u00b10.3) in its x-ray diffraction pattern. It also relates to a preparation method of the form III of compound 4 - (2 - (4,4 '- di Oxooxazolidin - methyl - 2 - 3 - il) thiazol-4-yl) benzonitrile.The polymorphic form is useful in the treatment of contraception, fibroids, benign and malignant neoplastic disease, among other
