Description
Technical field
The present invention relates to a kind of method of industrialized production Moxifloxacin hydrochloride.Moxifloxacin hydrochloride is a fluoroquinolone antibiotics, can be used for treating responsive microbial infection.
Formula I
Technical background
Moxifloxacin hydrochloride (Moxifloxacin hydrochloride) is the ultra wide spectrum quinolone antibiotic of Beyer Co., Ltd's development; Chemistry is by name: 1-cyclopropyl-6-fluoro-1; 4-dihydro-8-methoxyl group-7-[(4 α S; 7 α S)-octahydro-6H-pyrrolo-[3,4-b] pyridine-6-yl]-4-oxo-3-quinoline carboxylic acid hydrochloride.Its chemical structural formula is suc as formula shown in 1.
Moxifloxacin hydrochloride goes on the market in Germany in September, 1999 first, obtains the FDA approval December and goes on the market in the U.S..Keeping on the outstanding active basis of the anti-gram-negative bacteria of early stage fluoroquinolone; Anti-gram positive organism and atypia pathogenic agent have obviously been strengthened (like mycoplasma, chlamydozoan; Legionella and anerobes etc.) activity; Clinical being mainly used in treated acute sinus gland inflammation, the acute attack of chronic bronchitis, community acquired pneumonia, and uncomplicated skin infections and skin soft-tissue infection.
These article have broad-spectrum antibacterial activity, especially Gram-positive, mycoplasma, chlamydozoan, legionella isoreactivity are much better than CIPROFLOXACIN USP 24, and effective to anerobes.The human body long half time, 1 400mg of administration every day can reach encouraging result.Clinical being mainly used in treated acute sinus gland inflammation, the acute attack of chronic bronchitis, community acquired pneumonia, and uncomplicated skin infections and skin soft-tissue infection.The characteristics of these article are almost not have photosensitized reaction, are considered to " the treatment respiratory tract infection is near the ideal medicine ".
Moxifloxacin hydrochloride is synthetic to be shown in EP550903 the earliest, discloses structure and a kind of breadboard compound method of Moxifloxacin, has adopted parent nucleus 1-cyclopropyl-6; 7-two fluoro-8-methoxyl groups-1, and 4-dihydro-4-Oxoquinoline-3-carboxylic acid ethyl ester and side chain (s, s)-2; The method of 8-diazabicyclo [4.3.0] nonane condensation; Can prepare target compound through this method, but post-treating method is complicated extracting operation and a column chromatogram chromatography purifying of multistep, when suitability for industrialized production, is difficult to realize.
Patent CN02131962 discloses and a kind ofly in water and alcoholic solution, has reacted the method that makes Moxifloxacin hydrochloride with 8-BAY 128039 carboxylic acid derivative and potassium tert.-butoxide or sodium tert-butoxide.Its post-treating method is in reaction solution, to be added dropwise to Hydrogen chloride, and adds crystal seed, stirring and crystallizing.The gained crystal filters, and aqueous solution recrystallization can obtain the Moxifloxacin hydrochloride product.This method is simpler relatively, but product loss is bigger in reaction solution, has reduced yield, and needs to add the crystal seed crystallization.
Patent CN101817820 discloses the side chain compound (s with the Boc protection; S)-2; 8-diazabicyclo [4.3.0] nonane prepares the method for Moxifloxacin hydrochloride; Its method is that gained Moxifloxacin bullion is added stirring and crystallizing in the Hydrogen chloride, filters, and a large amount of frozen water washings obtain the Moxifloxacin hydrochloride bullion.There is the big shortcoming of product loss in same this method.
The prescription of Moxifloxacin hydrochloride sodium-chlor preparation is disclosed among the patent CN1368891; And the solubleness of 5 ℃ of following Moxifloxacin hydrochlorides in the sodium chloride solution of 0～0.9% concentration is provided in specification sheets; The solubleness of Moxifloxacin hydrochloride reduces with sodium chloride concentration from 0 to 0.9%.But this patent does not relate to the influence to Moxifloxacin hydrochloride solubleness of other temperature and 0.9% above concentration sodium chloride aqueous solution, finds to utilize saltouing of high density can in industry, prepare highly purified Moxifloxacin hydrochloride.
In research process; The discovery that we are surprised; The solubleness of Moxifloxacin hydrochloride in water is along with the reduction of temperature and the increase of sodium chloride concentration descend rapidly; In 1% above sodium chloride solution, can reach fully, from the aqueous solution, precipitate and isolate the purpose of highly purified Moxifloxacin hydrochloride with acceptable yield.This method is never seen and is applied in Moxifloxacin hydrochloride synthetic.
Utilize this characteristic, we have invented a kind of method of industrialized production Moxifloxacin hydrochloride, and the Moxifloxacin hydrochloride yield of producing through this method is high, and quality is good, can guarantee the single impurity of products obtained therefrom less than 0.1%, and total impurities is less than 0.2%.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operate, mild condition, yield is higher and be easy to the working method of industrialized Moxifloxacin hydrochloride.Through a large amount of evidences, present method has extremely strong industriallization feasibility, can stablize the control quality product, obtains that highly purified Moxifloxacin hydrochloride list is assorted to be no more than 0.1%, always assortedly is no more than 0.2%.
Particularly, working method of the present invention is: following solid sodium chloride or sodium chloride aqueous solution, the insulated and stirred crystallization of adding of aqueous solution stirring that will contain Moxifloxacin hydrochloride through synthetic; Filter water recrystallization, 0～40 ℃ of crystallization; Filter, air blast or vacuum-drying promptly get product.
