Abstract

The invention provides a cyclopropanecarboxamide derivative F crystal form (please see the specification for the formula) in the formula (I). According to the XRPD illustration of the crystal form, diffraction peaks exist when 2Q is equal to 8.717, 9.758, 10.299, 10.8, 12.879, 15.401, 16.64, 16.92, 17.859, 18.759, 19.499, 20.678, 22.841, 23.178, 23.88, 24.479, 25.958, 27.06, 28.039, 29.521 and 31.121, and the error range of the 2Q value is + / -0.2. The cyclopropanecarboxamide derivative F crystal form has good high-temperature stability, high-humidity stability and illumination stability. Moreover, low moisture absorption performance is achieved. The cyclopropanecarboxamide derivative F crystal form can be applied to drugs for treatment or prevention of JAK-participated inflammation and autoimmunity diseases, proliferative diseases, graft rejective reactions and congenital cartilage deformation or diseases caused by IL6 oversecretion, and good bioavailability is achieved. Meanwhile, qualitative and quantitative information is provided, which is of important significance to further studying the curative effect of the solid drugs.

Description

technical field [0001] The present invention relates to a polymorphic form of a cyclopropanecarboxamide derivative as a JAK inhibitor, in particular to a crystal form F of a cyclopropanecarboxamide derivative and a preparation method thereof. Background technique [0002] JAK is Janus Kinase, which is a non-receptor tyrosine protein kinase and a non-transmembrane tyrosine kinase. This is because JAK can not only phosphorylate the cytokine receptors associated with it, but also phosphorylate multiple signaling molecules containing specific SH2 domains. The JAK protein family includes 4 members: JAK1, JAK2, JAK3 and TYK2, which have 7 JAK homology domains (JAKhomology domain, JH) in their structure, of which the JH1 domain is the kinase domain and the JH2 domain is the "false" The kinase domain, JH6 and JH7 are receptor binding domains. [0003] TYK2 is a potential target for immunoinflammatory diseases, which has been confirmed by human genetics and mouse knockout studies (...
