Definitions
- a process of this type is also described in WO-A-98/33774 which consists in carrying out the hydrolysis of the ester function followed by acidification, separation by filtration of the 4-hydroxy-3-quinolinecarboxylic acid then obtained from a decarboxylation step between 190 and 240 ° C, preferably between 210 and 230 ° C.
- a quinoleic compound is used.
- quinolinic compound is understood a heterocyclic compound comprising a quinol pattern 'ine. This term is also used for the naphthypyridine type compounds which are also included in the process of the invention.
- the heterocycle of the quinoleic compound carries at least one hydroxyl group in position 4 and an ester functional group in position a of the hydroxyl group.
- Other substituents can also be present in particular in position 5 and / or 7.
- the starting quinoleic compound of the invention can be symbolized by the following general formula:
- - R- j identical or different, represent:. an alkyl group, linear or branched, having from 1 to 12 carbon atoms, preferably from 1 to 4 carbon atoms, such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl ,. an alkyl group, carrying one or more halogen atoms, linear or branched, having from 1 to 6 carbon atoms, preferably from 1 to 4 carbon atoms, such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl,.
- a linear or branched alkenyl group having from 2 to 12 carbon atoms, preferably from 2 to 4 carbon atoms, such as vinyl, allyl,. a cyclohexyl phenyl or benzyl group. . a linear or branched alkoxy or thioether group having from 1 to 6 carbon atoms, preferably from 1 to 4 carbon atoms such as the methoxy, ethoxy, propoxy, isopropoxy, butoxy radicals,
- a halogen atom preferably a chlorine or bromine atom
- a trifluromethyl group an alkenylene group having 3 or 4 carbon atoms capable of forming a ring with the carbon atoms adjacent to the phenyl ring,
- - n is a number between 1 and 4, preferably equal to 1 or 2.
- substituents R- are chlorine atoms, a methyl or methoxy radical.
- R 2 it is not critical insofar as the carboxylate group is eliminated. It is for economic reasons, essentially an alkyl group, linear or branched having from 1 to 12 carbon atoms, preferably from 1 to 4 atoms this carbon but i! is possible to have other groups, for example cyclohexyl, phenyl or benzyl or any other group.
- alkyl esters having from 1 to 4 carbon atoms of 4-hydroxyquinoline carboxylic acids. Mention may more particularly be made of the alkyl esters of 4-hydroxy-7-chloroquinoline carboxylic acid, 4-hydroxy-5-chloroquinoline carboxylic acid, 4-hydroxy-5,7-dichloroquinoline carboxylic acid.
- methyl or ethyl 4-hydroxy-5,7-dichloroquinoline-3-carboxylate is used in the process of the invention.
- R-,, R 2 and n have the meanings given above for formula (I).
- the hydrolysis is carried out with water in liquid and / or vapor form.
- the amount of water used is preferably at least equal to the stoichiometric amount, and more preferably in the presence of an excess which can be very large, for example 20 times the stoichiometric amount.
- the water is in excess ranging from 5 to 15 times the stoichiometric amount.
- Decarboxylation is obtained either by heating the reaction mixture, in the absence of any organic solvent at its melting point or at a temperature slightly below its melting point in the event of decomposition of the starting product, or by heating in the presence an organic liquid with a high boiling point of the heat transfer type.
- the decarboxylation temperature is preferably greater than or equal to 200 ° C, preferably between 200 ° C and 250 ° C, and even more preferably between 230 ° C and 240 ° C.
- a temperature higher than 250 ° C can be chosen depending on the nature of the organic liquid. She is around 270 ° C when using a paraffinic oil.
- a preferred organic liquid for this type of reaction is the eutectic mixture of biphenyl oxide and biphenyl referenced by the trade names of THERMINOL VP1, DOWTHERM or GILOTHERM DO.
- the decarboxylation temperature is advantageously chosen in the preferred temperature zone.
- the quinoleic compound is generally introduced into the abovementioned organic liquid in an amount, for example from 10 to 50%, preferably between 10 and 30% of the total weight of the reaction mixture, then gradually heats up to the chosen decarboxylation temperature (0.5 to 1 ° C per minute). It is not necessary for all the starting material to be dissolved in the reaction medium.
- the precipitate is separated according to conventional solid-liquid separation techniques, preferably by filtration.
- water or a solvent having a low boiling point for example less than 150 ° C and preferably between 60 ° C and 120 ° C, can be used.
- solvents mention may be made of: o-dichlorobenzene, methylcyclohexane, benzene, toluene, chlorobenzene, methanol or ethanol.
- the decarboxyated product is thus obtained with very good yield without having the problem of neutralization and elimination of the catalyst.
- the invention applies very particularly to the preparation of 4-hydroxy-
- 7-halo-quinoline preferably 4-hydroxy-7-chloroquinolein and its isomer
- 4-hydroxy-5-halo-quinoline preferably 4-hydroxy-5-chioroquinolein. It is quite well suited for the preparation of 5,7-dichloro-4-hydroxyquinoline.
- Therminol 210 ml of Therminol are introduced into a stirred reactor fitted with a distillation column, a water injection system and heated by an oil bath.
- the temperature of the reaction mixture obtained above is lowered to 230 ° C. and 10.4 g (0.58 mol) of water is injected continuously by means of a tube flush with the surface of the reaction mixture for 3 h 20 min.
- Example 2 a - Preparation of ethyl 4-hydroxy-5.7-dichloroquinoline-3-carboxylate: From 33.5 g (0.155 mol) of ethyl ethoxymethylene malonate, 24.3 g (0.15 mol) of 3,5-dichloroaniline and 263 g of Therminol VP1, the suspension of ethyl 4-hydroxy-5,7-dichloro-quinoline 3-carboxylate is prepared as described in Example 1. b - Hydrolysis - decarboxylation of the ethyl 4-hvdroxy-5,7-dichloroquinoline-3-carboxylate obtained:
- the temperature of the reaction mixture obtained above is lowered to 240 ° C. Is injected, by means of a tube immersed in the reaction mixture,
