Description
Technical field
The present invention relates to a kind of method for producing amorphous Dasatinib, belongs to pharmaceutical technology field.
Background technology
Dasatinib (BMS-354825, Dasatinib) is a kind of tyrosine kinase inhibitor, for treating Imatinib
(Imatinib) treat the later stage chronic granulocytic leukemia (Chronic Myelogenous Leukemia, CML) and
The acute myeloid leukaemia that Philadelphia chromosome is positive, the current medicine are also proved to treat the cancer of many other types, such as
Prostate cancer of accelerated period etc..
The preparation method of the Dasatinib disclosed by document is concentrated mainly in the synthesis of the various crystal formations of Dasatinib at present,
And rarely have disclosure for how to prepare amorphous Dasatinib.What the CN 1980909 as authorized was protected is that one, band is crystallized
The Dasatinib of water, i.e. its monohydrate crystal form, and the preparation method of the monohydrate crystal form is disclosed, but do not refer to nothing
The preparation of setting Dasatinib.CN103059013 is found that the novel crystal forms of Dasatinib -- the crystal formation of Dasatinib monohydrate
III, and the preparation method of the crystal formation is disclosed, but also it is not directed to amorphous Dasatinib.CN102643275 discloses one kind
The preparation method of Dasatinib N-6 crystal formations, CN102086195 disclose a kind of the polymorph of Dasatinib (mixed crystal) open
Its preparation method and the Pharmaceutical composition comprising the polymorph, these documents are all not related to the system of amorphous Dasatinib
It is standby.
However, Dasatinib crystal formation effect in the production process of Subsequent pharmacological preparation is sometimes unsatisfactory, because up to sand
It is slow for dissolution velocity of Buddhist nun's crystal formation in pharmaceutical auxiliaries such as water or alcohols solvent, the production time of preparation is extended, no
Beneficial to pharmaceutical practice.
It has been investigated that, unbodied Dasatinib, can almost in various pharmacy solvents such as water or alcohols solvent
Enough quick dissolvings, solubility are high, are conducive to pharmaceutical practice, can significantly shorten the production time of preparation, reduce pharmaceutical preparation
The loss of Dasatinib in production process.
CN103408542 discloses a kind of preparation method of highly purified Dasatinib anhydride, and which is by N- (the chloro- 6- of 2-
Aminomethyl phenyl) -2- [(6- chloro-2-methyl -4- pyrimidine radicals) amino] -5- thiazole carboxamides and N- hydroxyethyl piperazines reaction be obtained reach
Husky to replace Buddhist nun's crude product, an one-step refining of going forward side by side is into highly purified Dasatinib anhydride.Wherein mainly include will be obtained for subtractive process
Dasatinib crude product heating for dissolving carries out air-distillation in absolute ethyl alcohol and DMF, then and removes solvent, Jing after filtering cooling,
Methyl tertiary butyl ether(MTBE) or isopropyl ether is added in filtrate, continues cooling crystallization, wash filter cake afterwards with ether solvent, and vacuum is dry
Dry 8-10 hours, obtain Dasatinib anhydride.Although obtained Dasatinib purity is high for the method, and water content is low, but refined
The yield of process is relatively low, and only 70% or so.Because the process for purification is complicated, operating procedure is various, using multi-solvents, therefore easily
Dasatinib is caused to lose.
Therefore, a kind of preparation method of amorphous Dasatinib is found, which can be greatly improved and prepare yield, farthest
The loss of Dasatinib is reduced, is one of Dasatinib preparation field technical problem urgently to be resolved hurrily.
