Abstract
The invention provides a method for preparing a quinazoline compound, in the method, the compound in a form of salt is directly used as a raw material, the reaction step is shortened, the number of used agents is decreased and the cost is lowered.
Description
Technical field
The present invention relates to organic chemistry and pharmaceutical chemistry field, particularly, relate to a kind of quinazoline compound, i.e. the preparation method of lapatinibditosylate.
Background technology
A kind of quinazoline compound, be specially, US Patent No. 6713485 (title: heterocyclic compound (Heterocyclic compounds), patentee: Smithkline Beecham Corp (SmithKline Beecham Corporation), publication date: on March 30th, 2004) a kind of medicinal compound that can be used for human body of report, name is called lapatinibditosylate, and structure is suc as formula shown in (I):
Its English Lapatinib by name; chemistry is by name: the chloro-4-[(3-fluorophenyl of N-[3-) methoxyl group] phenyl]-6-[5[[[2-(methylsulfonyl) ethyl] amino] methyl]-2-furyl]-4-quinazoline amine (N-[3-Chloro-4-[(3-fluorophenyl) methoxy] phenyl]-6-[5[[[2-(methylsulfonyl) ethyl] amino] methyl]-2-furanyl]-4-quinazolinamine); cas number is 231277-92-2, molecular formula: C29H26ClFN4O4S.
It is a kind of PTS, and its tosilate monohydrate is in Nikkei united States food and drug administration (FDA) approval listing March 13 in 2007.This medicine is a kind of kinase inhibitor, mainly by multipath, deprives the needed bio signal of growth of tumour cell and brings into play antitumor action.It can be combined with another kind of anticarcinogen capecitabine (capectabine) and uses treatment to shift HER2 positive breast cancer late period.Than this high molecular weight protein monoclonal antibody of Herceptin (trastuzumab), lapatinibditosylate is a kind of micromolecular compound, can enter the function that stops some albumen in cell, can treat the inoperative mammary cancer of Herceptin with it.
The method of preparing lapatinibditosylate has description in patent US6713485, it is to use as shown in the formula (1) compound (5-(4-(4-(3-fluorine benzyloxy)-3-chlorobenzene is amino)-6-quinolyl)-2 furan carboxyaldehyde) and formula (2) compound (methylsulfonyl ethamine) to do raw material, first generate western Buddhist alkali, then going back under the condition of original reagent sodium triacetoxy borohydride existence, reduction C=N key makes target product.Concrete route is as follows:
Wherein compound (1) and compound (2) are all monomeric compounds.Their synthetic method is as described below:
1. the synthetic route of compound (1) is:
Note: R1 wherein, R2 represents alkyl
Sloughing after aldehyde radical protecting group with acid (example hydrochloric acid), obtain hydrochloride compound (II); Then add alkali (as sodium hydroxide, sodium carbonate or salt of wormwood etc.) and carry out neutralization reaction, obtain compound (1).
2. the synthetic route of compound (2) is:
In by acid (as tosic acid) deaminize protecting group (tertbutyloxycarbonyl), obtain compound (III); Then add alkali neutralization compound (III) and obtain monomeric compound (2).
Another piece of US Patent No. 7157466 (title: quinazoline ditosylate salt compounds (Quinazoline ditosylate salt compounds), patentee: Smithkline Beecham Corp (SmithKline Beecham (Cork) Limited), publication date: the preparation method who on January 2nd, 2007) has announced again a kind of lapatinibditosylate, the difference of itself and previous method is, the compound of one of raw material (1) is changed into the form (as shown in the formula compound shown in (4)) of its tosilate, and compound (4) is to obtain by hydrochloric acid 5-(4-(4-(3-fluorine benzyloxy)-3-chlorobenzene is amino)-6-quinolyl)-2 furan carboxyaldehyde (being described formula (II) compound) conversion, process is more loaded down with trivial details.Concrete route is as follows:
Wherein, THF represents tetrahydrofuran (THF), and IPA represents Virahol.
Patent WO2008024439 (date of publication: the route of on February 28th, 2008) announcing is as follows:
In this route, monomeric compound (1) and methylsulfonyl ethamine monomer generate western Buddhist alkali, are also with sodium triacetoxy borohydride reduction, also will protect amido with Boc, and main purpose should be to guarantee that amido is NH rather than ND; The de-Boc of last hydrochloric acid, and use tosic acid salify, process is also comparatively loaded down with trivial details.
Can draw thus, prior art is for the preparation of quinazoline compound lapatinibditosylate, being all to use monomeric compound (1) (or its tosic acid salt compound (4)) and monomeric compound (2) as raw material, is all that the compound of salt form reacts and do not use raw material; Monomer (or its tosilate) also needs first with the compound of other salt form, to change, and makes undoubtedly reactions steps increase by a step, and cost is increased, and causes yield to reduce.And methylsulfonyl ethamine monomer itself is liquid, even free, also be inconvenient to process, if but form salt, easily processing is a lot.And in existing method, reductive agent is all with sodium triacetoxy borohydride, not only expensive, and atom utilization is quite low, yield is not high yet.
Summary of the invention
Object of the present invention is exactly for the problems referred to above and deficiency, provides a kind of preparation method of quinazoline compound, more properly, a kind of method of preparing lapatinibditosylate is provided, and the method is directly used the compound of salt form to do raw material, and reactions steps shortens, agents useful for same reduces, cost.
To achieve these goals, the technical solution used in the present invention is as follows:
A preparation method for quinazoline compound, is characterized in that, reaction scheme is as follows:
Wherein, HX is mineral acid or organic acid; Mineral acid can be haloid acid or sulfuric acid etc.; Organic acid can be tosic acid, fumaric acid, tartrate or acetic acid etc.; Preferred hydrochloric acid, acetic acid.
HY is hydrochloric acid or tosic acid (TsOH) etc.; Preferred tosic acid.
The present invention uses 5-(4-(4-(3-fluorine benzyloxy)-3-chlorobenzene is amino)-6-quinolyl)-2 furan carboxyaldehyde hydrochlorate (compound (II)) and methylsulfonyl ethamine hydrochlorate (compound (III)) to do raw material, and reaction obtains quinazoline compound lapatinibditosylate (compound (I)).
Further, in reaction process, compound (II) directly reacts with compound (III) and generates western Buddhist alkali, i.e. compound (3) shown in following structure:
Western Buddhist alkali reduces with metal borohydride, obtains described lapatinibditosylate (Compound I).
Further, described metal borohydride can be selected from: sodium borohydride (NaBH
4) or POTASSIUM BOROHYDRIDE (KBH
4).
Further, can in reaction process, add Lewis acid, improve reducing power, make reduction effect better, use metal borohydride and lewis acidic combination, can be selected from: NaBH
4/ LiBr, NaBH
4/ LiCl, KBH
4/ LiBr, NaBH
4/ CH
3cOOH or NaBH
4/ I
2deng; NaBH most preferably
4/ LiBr.
Further, in reaction process, the solvent using is ether solvent, preferably tetrahydrofuran (THF) (THF).
Further, temperature of reaction is controlled at 10~70 ℃, preferably 20~30 ℃.
Beneficial effect of the present invention is as follows:
(1) processing condition are reasonable, directly with the reaction of salt form compound, generate western Buddhist alkali, need not as method described in patent US7157466, adjust especially compound (II) is tosilate, also without patent US6713485, announce route and like that compound (II) is dissociated into monomer with compound (III), this point just reduces single step reaction process than two kinds of methods of patent.
(2) reducing activity that utilizes Lewis acid to improve sodium borohydride replaces sodium triacetoxy borohydride to reduce, and not only with low cost, Atom economy is high.And the stability of sodium borohydride itself is also good more than sodium triacetoxy borohydride, does not resemble sodium triacetoxy borohydride and be easy in storage process because the moisture in ingress of air decomposes rotten.And methylsulfonyl ethamine directly participates in reaction with salt, rather than free alkali, also easier than patented method.
In sum, the present invention directly uses the compound of salt form to do raw material, has shortened reactions steps, and agents useful for same reduces; And replace expensive sodium triacetoxy borohydride with sodium borohydride, and make material used cheap and easy to get, cost, Atom economy is high, has avoided sodium triacetoxy borohydride to store the inconvenience of transportation, has larger suitability for industrialized production advantage.
