Definitions
- the present invention relates to a process for the preparation of quinolonecarboxylic acid, and more particularly to a process for preparing a quinolonecarboxylic acid using polyhaloacetophenone as a starting material.
- Quinolone anti-infective drugs have received widespread attention in recent years due to their excellent properties.
- Quinolone carboxylic acid is an important intermediate for such anti-infective drugs.
- Various quinolones are not derived from these intermediates and are synthesized by several steps. Therefore, the synthesis of these quinolonecarboxylic acids is obviously very important in the preparation of quinolones.
- One of the objects of the present invention is to provide a novel process for the preparation of quinolonecarboxylic acid from the synthesis of quinolonecarboxylic acid from the starting polyhaloacetophenone.
- the method steps of the present invention are relatively small, and a relatively desirable yield can be achieved.
- a process for preparing a quinolonecarboxylic acid of the formula (I) of the present invention is relatively small, and a relatively desirable yield can be achieved.
- ⁇ is a halogen atom, an amino group
- R 2 is a halogen atom
- R 3 is hydrogen, a halogen atom, ( ⁇ - ⁇ oxy, CN,
- 1 4 is 3 - (3 6 cyclodecyl, fluorenyl, (C 4 methoxy CC 4 fluorenyl, cc 4 cc 4
- RR 2 and R 3 have the same meanings as defined above, and R 7 is a halogen atom.
- R 8 represents a methyl group or an ethyl group
- Rj is H, C1;
- R 2 is C1
- R 3 is F, ( ⁇ -( 4 alkoxy, CN;
- the compound of the formula (I) is preferably hydrogen, fluorine or amino, preferably fluorine or chlorine; R 3 is preferably fluorine, CN or OCH 3 ; preferably cyclopropane Base, cyclohexyl.
- the reaction of the compound of the formula (II) with a carbonate can be carried out with methyl carbonate or ethyl ester, and the reaction is usually carried out in an organic solvent in the presence of a base. It is preferred to use the carbonate itself as a solvent, and the base used may be selected from sodium hydride or sodium alkoxide.
- the reaction of the compound of formula (III) with the orthoformate is usually carried out in the presence of acetic anhydride, and after the reaction, it is directly reacted with R 4 NH 2 of the formula (IV) to give a compound of the formula (V).
- the cyclization of the reactant of the formula (V) is carried out in an organic solvent under basic conditions, preferably DMF is used as the solvent, and anhydrous potassium carbonate is optionally used as the base to obtain a compound of the formula (VI).
- anhydrous potassium carbonate is optionally used as the base to obtain a compound of the formula (VI).
- the corresponding quinolone carboxylate is hydrolyzed to the corresponding carboxylic acid of the formula 00 by conventional methods in the art.
- R 1 when R 1 is NH 2 , it can be converted from a compound of the formula (VI) wherein the halogen is corresponding, and the reaction is as follows:
- R 3 is preferably F, OCH 3 , CN.
- the formula ( ⁇ ) is carried out by a plurality of methods in the preparation of the compound.
- the present invention is carried out from a readily available polyhalogenated benzene.
- the invention is further illustrated by the following specific examples. Preparation of quinacridone
- reaction mixture was poured into 800 ml of ice water, and the solid was filtered, washed with water (100 ml), and then dried, and then evaporated to 15 5,7,8-tetrafluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid ethyl ester 53.0 g (0.161 mol), mp 169-171 ° C, yield 93%.
- the solvent was evaporated, and the residue was crystalljjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
- the material was poured into 170 g of crushed ice containing 75 ml of 25% sulfuric acid and stirred for 5 minutes.
- the organic phase was separated and the aqueous layer was extracted with toluene.
- the organic layer was combined, washed sequentially with aqueous sodium chloride solution, aqueous sodium hydrogen carbonate and water and dried over anhydrous sodium sulfate.
- the material was poured into a 1,000 ml aqueous solution containing 12.4 g of NaHSO 3 , allowed to stand overnight, filtered, washed 3-4 times with warm water (about 30 Torr), and dried to obtain 2,4,6-trichloro-3,5- 34.1 g (0.115 mol) of difluorobromobenzene, yield 92.9%.
- reaction temperature was raised to room temperature and stirred for 3 hours.
- the reaction mass was poured into 150 g of crushed ice containing 75 ml of dilute sulfuric acid (25%) and stirred for 5 minutes.
- the organic layer was separated and the aqueous layer was extracted with toluene 30 ml.
- the organic layers were combined, washed successively with 45ml, 45ml ,, saturated aqueous NaHC0 3 and saturated aqueous NaCl 45ml water 25ml with saturated aqueous NaCl.
