Abstract
The invention provides a new preparation method of an alpha crystal form of imatinib mesylate. The method comprises the following steps: suspending imatinib in the mixed solvent of organic solvent and water, and then adding methylsulphonic acid to obtain the alpha crystal form of imatinib mesylate.
Description
Technical field
The present invention's design relates to the polymorph medicine preparing technical field, more specifically for relating to the preparation method that a kind of her agate replaces Buddhist nun's methane sulfonates alpha-crystal form
Background of invention
Yi Ma is 4-[(4-methyl isophthalic acid-piperazinyl again for Buddhist nun's methane sulfonates) methyl]-N-[4-methyl-3-[4-(3-pyridyl)-2-pyrimidyl] amino]-phenyl] the benzamide methane sulfonates, its structural formula is suc as formula shown in the I:
Formula I
Yi Ma is a kind of protein-tyrosine kinase inhibitor of being developed by Switzerland Novartis Co.,Ltd for Buddhist nun's methane sulfonates, it is effective especially in all types of treatment for cancer, is widely used in the chronic phase patient after treatment chronic myelocytic leukemia (CML) acute transformation phase, acceleration period or alpha-interferon treatment are failed at present; Can not excision or malignant gastrointestinal mesenchymal neoplasm (GIST) patient that shifts is taken place, with oral form administration, the market requirement is bigger usually.
Up to the present, according to bibliographical information, Yi Ma is for Buddhist nun's methane sulfonates total α, β, δ, ε, α 2, H1, I, II, F, G, K, H, I, K, IV, V, VI, VII, VIII, IX, X, XI, XIII, XIV, XV, XVI, amorphous, totally 27 kinds of crystal formations.Wherein beta crystal is that the listing crystal formation is subjected to Novartis Co.,Ltd's patent protection, and all the other crystal formation patents are new or be solvate, and alpha-crystal form has not had patent protection at present, and had similar physico-chemical property with beta crystal, so be studied more as one of crystal formation of discovery early.In W09903854, her agate is suspended in the ethanol for the Buddhist nun, drips methanesulfonic, the high temperature reflux cooling crystallization makes, but this method yield is low, and dissolvent residual exceeds national standard; CN101573350A mentions multiple her special agate and replaces Buddhist nun's methane sulfonates preparation method, and product is separated out soon in these method salification process, can't filter purification, and controllability is bad, concurrent existing mixed crystal phenomenon.WO2005095379 replaces the Buddhist nun to be suspended in the mixed solvent of ethanol and C1~C6 alcoholic solvent her agate, and high temperature drips methanesulfonic, drips ester badness solvent then, cooling crystallization, this method solvent load is excessive, and the salification process product is separated out soon, can't filter purification.Patent WO2006024863 is suspended in the single alcohol kind solvent of C3~C5 with her agate for the Buddhist nun, drips methanesulfonic, the high temperature reflux cooling crystallization, and this method also is to have the problem that dissolvent residual can't be qualified.WO2006048890 is that her agate that will prepare replaces Buddhist nun's methane sulfonates to be dissolved in the mixed solvent of C1~C4 alcohol and water, and by Rotary Evaporators concentrating under reduced pressure evaporate to dryness, this method has mixed crystal phenomenon, and is not easy to industrialization.More than the methods introduced of five pieces of patent applications, mainly have mixed crystal phenomenon, problem such as repeatability is bad, and dissolvent residual is defective, and reaction volume is excessive, and reaction process is uncontrollable is so cause it to be subjected to certain limitation in course of industrialization.
Summary of the invention
The present invention improves on the basis of WO2005095379 and WO2006048890, by replacing her agate the optimum solvent and the poor solvent of Buddhist nun's methane sulfonates to be mixed with mixed solvent with certain proportion, reaction cumulative volume and the solubleness of product in mother liquor have effectively been regulated by the water that adds certain ratio again, add methanesulfonic one step salify then, add a small amount of α crystal seed again and induce crystallization to make her agate for Buddhist nun's methane sulfonates alpha-crystal form.This method has well solved the problem that alcoholic solvent exceeds standard, and whole salification process controllability, favorable reproducibility, and strong operability has good industrial application value.
The reaction that the present invention relates to is suc as formula shown in the II:
