Description
Technical field
The present invention relates to a kind of medicinal crystal formation and preparation method thereof that is fit to of antipsychotic drug Aripiprazole (aripiprazole).
Background technology
Aripiprazole is a kind of atypical antipsychotic agents, is used for the treatment of schizophrenia.The chemistry of Aripiprazole is called 7-[4-[4-(2, the 3-dichlorophenyl)-1-piperazinyl] butoxy]-3,4-dihydro-2 (1H)-quinolinone, the CAS accession number is 129722-12-9, chemical structural formula is:
PCT patent application WO 03/026659 discloses six kinds of anhydrous aripiprazole crystal formations such as B, C, D, E, F and G and preparation method thereof.Wherein, water absorbability is low and be applicable to the preparation of the anhydrous aripiprazole crystallization B of pharmaceutical preparation, and the Aripiprazole monohydrate A that needs to prepare especially is at 100 ℃ of heating 18h, then at 120 ℃ of heating 3h.This method is not only consuming time but also consume energy.
Summary of the invention
We find, can by with the Aripiprazole heating for dissolving in suitable organic solvent, adopt one of following two kinds of methods that crystallization is separated out fast and equably then: method one, crystallization in cooling fast and under stirring; Method two a kind ofly separates out crystallization to the less solvent of Aripiprazole solubleness by adding.The crystallization that filter collection is separated out, only need dry remove desolvate after, it is low and be applicable to the stable anhydrous aripiprazole crystal formation (to call the alpha-crystal form anhydrous aripiprazole in the following text) of pharmaceutical preparation to obtain a kind of water absorbability.This crystallization processes need not special operation, and province's energy saves time.
The Aripiprazole as starting raw material that is adopted can be pure product or crude product according to Chinese patent CN1028104C or Chinese invention patent application CN1504461A (application number is 02150807.0) preparation; Can comprise various crystal formations, as I type, II type, B, C, D, E, F, the G and composition thereof etc. that set forth among the WO 03/026659.
The organic solvent that crystallization method one is adopted can be lower alcohol (as dehydrated alcohol), acetonitrile or toluene, and the rate of cooling scope is 3-60 ℃/min, and the stir speed (S.S.) scope is 10-900rpm.The concentration of recrystallization mother liquor can be that every gram Aripiprazole is dissolved in 4-50 milliliter recrystallization solvent, and better every gram Aripiprazole is dissolved in 6-30 milliliter recrystallization solvent, and preferably every gram Aripiprazole is dissolved in 8-12 milliliter recrystallization solvent; If with the recrystallization solution of the heat crystallization of under agitation slowly lowering the temperature, perhaps leave standstill crystallization, to can not get the alpha-crystal form anhydrous aripiprazole, but obtain the relatively poor crystal formation of a kind of solubleness (to call the beta crystal anhydrous aripiprazole in the following text) (fusing point 147.4-148.2 ℃ respectively has an endotherm(ic)peak (heating rate 10.00 ℃/min)) near 150.666 ℃ and 149.939 ℃ in differential thermal analysis (DSC) collection of illustrative plates.
The mixed solvent that the organic solvent that crystallization method two is adopted is made up of a kind of solvent (as tetrahydrofuran (THF), ethyl acetate or methylene dichloride) bigger to Aripiprazole solubleness and the another kind of solvent (as normal hexane or normal heptane) less to Aripiprazole solubleness.At first, Aripiprazole is dissolved in a kind of solvent bigger to Aripiprazole solubleness in room temperature to reflow temperature range; Look the difference of solubleness size, every gram Aripiprazole is dissolved in 0.5-50 milliliter solvent, better every gram Aripiprazole is dissolved in 1-30 milliliter solvent, and preferably every gram Aripiprazole is dissolved in 2-10 milliliter solvent.Then, under agitation add the another kind of solvent less to Aripiprazole solubleness, common every milliliter adds the solvent 1-10 milliliter less to Aripiprazole solubleness to needing in the bigger solvent of Aripiprazole solubleness, fully separates out to guarantee Aripiprazole.The stir speed (S.S.) scope is 10-900rpm.
Prepared alpha-crystal form anhydrous aripiprazole has following physico-chemical property:
(1) melting range is 138.5-140.5 ℃;
An endotherm(ic)peak (10.00 ℃ of heating rate/min) are arranged near 141.166 ℃ in (2) differential thermal analysis (DSC) collection of illustrative plates;
