Description
Technical field
The invention belongs to technical field of medicine synthesis, and in particular to one kind is about Brigatinib key intermediate (II)
Homogeneously " one kettle way " preparation method.
Background technique
Brigatinib, trade name Alunbrig, the Ariad drugmaker by now belonging to military field pharmacy research and develop listing,
FDA approval is obtained for the disease progression after gram azoles is for Buddhist nun (Crizotinib) treatment in April, 2017, or Buddhist nun is replaced not to gram azoles
The Locally Advanced or Metastatic Nsclc for the anaplastic lymphoma kinase positive (ALK+) being resistant to.In addition, suitable grinding
Answering disease further includes fibrosarcoma, diffusivity large B cell lymphoid tumor and primary cutaneous type etc..According to Thomson
Reuters data statistics prediction, Brigatinib will obtain 45,330,000 dollars of sales volume in 2017, then year by year on
It rises, is up to 4.78 hundred million dollars to annual sales amount in 2021, has good market prospects.
The chemical name of Brigatinib are as follows: the chloro- N2- of 5- [4- [(4- methylpiperazine-1-yl) piperidin-1-yl] -2- methoxyl group
Phenyl]-N4- [2- (dimethyl Asia phosphono) phenyl] -2,4- pyrimidinediamine (I), structure formula (I) is as follows:
Patent WO2009143389 reports the structure and synthetic method of (I) for the first time, document (J.Med.Chem.2016,
59,4948-4964) and international monopoly US2015225436, WO201665028 etc. also report the synthetic method of (I).Current
The synthetic method about (I) of report is as follows:
At present the synthetic method about key intermediate (II) be by 2- Iodoaniline and dimethyl phosphine palladium acetate/
Under Xantphos catalysis, with K3PO4For acid binding agent, coupling obtains (2- aminophenyl) dimethyl phosphine (IV), then with 2,4,5-
Trichloropyrimidine reacts to obtain (2- ((2,5- dichloro pyrimidine -4- base) amino) phenyl) dimethyl phosphine (II).Synthetic route is such as
Under:
There is apparent defect in the above-mentioned synthetic method about (II): the 1) synthesis of intermediate (IV) in the actual process
Cheng Fanying not exclusively, low efficiency, need column chromatographic purifying.2) yield is not high, and two-step reaction total recovery is only 49.9%
(J.Med.Chem.2016,59,4948-4964), and operating process is complicated, it is time-consuming and laborious, it is unfavorable for industrialized production.
From the foregoing, it will be observed that the prior art haves the defects that not high yield, low efficiency and cumbersome, it is to influence at present
An important factor for Brigatinib intermediate (II) industrialized production.New preparation method is developed to improve the production of intermediate (II)
Rate and combined coefficient are technical problems urgently to be solved.
Summary of the invention
In view of in existing method there are above-mentioned technical problem, the purpose of the present invention is develop it is a kind of it is easy to operate, high-efficient,
Yield is good, stable product quality and the environmental-friendly preparation method about (II).
" one kettle way " preparation method the present invention provides one kind about Brigatinib key intermediate (II), the system
Preparation Method includes:
2- Iodoaniline and dimethyl phosphine are subjected to coupling reaction under catalyst, acid binding agent effect, without isolation directly
It connects and carries out substitution reaction with 2,4,5- trichloropyrimidine.Then through extraction, washing, drying, filter, be concentrated to get crude product, pass through weight
Crystallization obtains (2- ((2,5- dichloro pyrimidine -4- base) amino) phenyl) dimethyl phosphine (II).
In preparation method of the present invention, 2- Iodoaniline: dimethyl phosphine: 2,4,5- trichloropyrimidines feed intake mole
Than for 1:1.1:1.2.
Coupling reaction temperature is 80~120 DEG C, preferably 90~100 DEG C.
The catalyst of coupling reaction is selected from palladium acetate/Xantphos, tetrakis triphenylphosphine palladium, palladium acetate/triphenylphosphine, excellent
It is selected as palladium acetate/Xantphos;Acid binding agent is selected from triethylamine, N, and N- diisopropylethylamine, triethylene diamine, 1,8- diaza are double
11 carbon -7- alkene of ring [5.4.0], 4-dimethylaminopyridine, pyridine, N-methylmorpholine, preferably n,N-diisopropylethylamine.2-
Iodoaniline: the molar ratio of acid binding agent is 1:2~2.5, preferably 1:2.2.
In recrystallization method of the present invention, the mixed solvent that selection is made of ethyl acetate and petroleum ether, preferably two
The volume ratio of person is ethyl acetate: petroleum ether=1:2.
Compared with prior art, key intermediate (II) preparation method of the present invention about Brigatinib has
Beneficial effect includes the following aspects: 1) replacing two-step reaction using homogeneous " one kettle way ", centre does not need to isolate and purify, and contracts
Short step simultaneously simplifies operation;2) than prior art raising, (yield of optimum condition is 67.2% to yield, is higher than document
The 49.9% of J.Med.Chem.2016,59,4948-4964 report);3) column chromatographic purifying is replaced with recrystallization, reduces solvent
Consumption and " three wastes " discharge.Therefore, preparation method of the present invention is easy to operate, efficiency and high income, environmental-friendly, is suitble to
Industrialized production.
Preparation method of the invention needs that otherwise " one kettle way " can not be passed through using homogeneous reaction, i.e. liquid-liquid homogeneous systems
Synthesis is to obtain above-mentioned beneficial effect.
