Description

A kind of cyclopropanecarbonyl amine derivative C crystal form and preparation method thereof
Technical field
The present invention relates to a kind of polymorphic of the cyclopropanecarbonyl amine derivative as JAK inhibitor, in particular it relates to one Plant cyclopropanecarbonyl amine derivative C crystal form and preparation method thereof.
Background technology
JAK is Janus kinases (Janus Kinase), is a kind of non-receptor type tyrosine protein kinase, is also that a class is non- The EGFR-TK of transmembrane.Because JAK can phosphorylation cytokine receptor combined with it, and can phosphorylation it is many The individual signaling molecule containing specific SH2 domains.JAK protein families include 4 members altogether:JAK1, JAK2, JAK3 and TYK2, They have 7 JAK homeodomains (JAK homology domain, JH) in structure, wherein JH1 domains be kinases area, JH2 domains are that "false" kinases area, JH6 and JH7 are receptorbinding regions.
TYK2 is the potential target spot of Immunoinflammatory Disorders, rejects research confirmation (Levy by people's science of heredity and mouse D. with Loomis C., 1655-1658 pages of New England Journal of Medicine 357 (2007)).
JAK1 is the novel targets in Immunoinflammatory Disorders field.By JAK1 and other JAK heterodimericization, with the transducer cell factor The pro-inflammatory signals conduction of driving.Therefore, it is contemplated that suppression JAK1 and/or other JAK is for a series of inflammatory conditions with other by JAK The disease of the signal transduction driving of mediation has treatment benefit.
Cyclopropanecarbonyl amine derivative, chemical name N- [5- [4- [(1,1- dioxo -4- thio-morpholinyls) methyl] phenyl] [1,2,4] triazol [1,5-A] pyridine -2- bases] cyclopropane carboxamide, as shown in formula (I),
A kind of JAK classes inhibitor compound, available for treat or prevent JAK participate in inflammation, autoimmune disease, Proliferative disease, graft-rejection and congenital cartilage deformity or with disease caused by IL6 hypersecretions.In middle promulgated by the State Council In bright patent CN 102105471 (WO 2010/010190), the synthetic method of the compound is disclosed;In Chinese invention patent In CN 102482273 (WO 2010/149769), the purposes of cyclopropanecarbonyl amine derivative is disclosed.Repeat above-mentioned patent Preparation method, obtains compound powder, is detected as amorphous state.Although as it is known by the man skilled in the art, amorphous big Most occasions all have higher solubility and dissolution rate than crystal formation, but its is unstable, and hygroscopicity is strong, easily switch to stable Crystal formation.Therefore, it is amorphous the problem of there is processing stability and bin stability, and in process of production, amorphous particle Bulk density it is smaller, surface free energy is high, also easily causes cohesion, poor fluidity, elastic deformation a series of formulation problems such as by force, Have a strong impact on the clinical drug use value of amorphous cyclopropanecarbonyl amine derivative.
It is well known that same medicine, crystal formation is different, its bioavilability may also can have difference, and it is stable in addition Property, mobility, compressibility may also can be different, application of these physicochemical properties to medicine produces certain influence, so that shadow Ring the curative effect of medicine.Accordingly, it would be desirable to the crystal formation of the cyclopropanecarbonyl amine derivative with superior physiochemical properties, it can have Sharply used in medicine processing and pharmaceutical composition.The novel crystal forms for the cyclopropanecarbonyl amine derivative that the present invention is developed do not appear in the newspapers Road.
The content of the invention
Problem to be solved by this invention is the unstability of existing cyclopropanecarbonyl amine derivative, hygroscopicity and easily turned The problems such as stable crystal formation, is unfavorable for medicine processing and is used in pharmaceutical composition, the new crystalline substance of cyclopropanecarbonyl amine derivative Type, the problem of providing more qualitative, quantitative information for the effectiveness study of solid drugs.
In order to solve the above-mentioned technical problem, the invention provides a kind of new crystal formation of cyclopropanecarbonyl amine derivative (with Call in the following text " cyclopropanecarbonyl amine derivative C crystal form "), as shown in formula (I).
Its XRPD collection of illustrative plates 2 θ=7.14,8.9,12.521,13.082,16.521,18.401,19.877,20.541, 21.517th, there is diffraction maximum at 21.825,24.04,24.764,25.3,26.359,27.5,28.719, wherein 2 θ value error ranges For ± 0.2.
According to the cyclopropanecarbonyl amine derivative C crystal form of the present invention, with substantially the same with Figure of description Fig. 1 XRPD collection of illustrative plates.
Present invention also offers a kind of method for preparing cyclopropanecarbonyl amine derivative C crystal form, comprise the following steps:In ring With 1 in cyclopropane carboxamide derivative:150~1:250g/mL ratio adds organic solvent, suspends at room temperature, then filter, Vacuum drying is so as to obtain the cyclopropanecarbonyl amine derivative C crystal form of off-white powder.
In certain embodiments, the organic solvent is alcohols or any one solvent or two or more molten in esters Agent is with the mixed solvent of arbitrary proportion.
In some preferred embodiments, the alcohol organic solvent is n-butanol;The based organic solvent is acetic acid Ethyl ester.
