Definitions

  • the invention relates to an improved process for preparing aminocrotonyl compounds such as for example 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline and the physiologically acceptable salts thereof, particularly 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline dimaleate, as well as 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-y
  • 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]-amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline has the following structure: and is already known from WO 02/50043, which describes compounds with valuable pharmacological properties, including in particular an inhibiting effect on signal transduction mediated by tyrosinekinases and an inhibitory effect on signal transduction mediated by the Epidermal Growth Factor receptor (EGF-R). Therefore, compounds of this type are suitable for the treatment of diseases, particularly for the treatment of tumoral diseases, diseases of the lungs and respiratory tract and diseases of the gastrointestinal tract and bile duct and gall bladder.
  • EGF-R Epidermal Growth Factor receptor
  • WO 02/50043 discloses a method of preparation wherein aminocrotonyl compounds (IV) such as for example 4-[(3-chloro4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline are prepared in a one-pot reaction from the corresponding aniline component (II), bromocrotonic acid (Ill), oxalyl chloride and a secondary amine (see Diagram 1).
  • Diagram 1 Diagram 1:
  • the aim of the present invention is to provide a process which allows the production of aminocrotonylarylamides, particularly 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline, using highly pure starting materials which are readily available and without any great technical expenditure.
  • This new process should therefore also be suitable for synthesis on an industrial scale and hence for commercial application.
  • the corresponding aminoaryl compound (V) is reacted with a di-(C 1-4 -alkyl)-phosphonoacetic acid, preferably with diethylphos-phonoacetic acid, in suitable solvents, after corresponding activation, preferably with 1,1 -carbonyldiimidazole, 1,1 -carbonylditriazole or propanephosphonic anhydride, particularly preferably with 1,1-carbonyldiimidazole, according to Diagram 2.
  • the solvent used may be for example tetrahydrofuran (THF), dimethylformamide (DMF) or ethyl acetate.
  • the activation may be carried out by any possible method of amide linking, i.e. for example with 1,1-carbonyidiimidazole, 1,1-carbonylditriazole, DCC (N,N-dicyclohexylcarbodiimide), EDC (N′-(dimethylaminopropyl)-N-ethylcarbodiimide), TBTU O-(benzotriazol-1-yl)-N,N,N′, N′-tetramethyluronium tetrafluoroborate, thiazolidine-2-thione or by conversion into the corresponding acid chloride, possibly using thionyl chloride.
  • 1,1-carbonyidiimidazole 1,1-carbonylditriazole
  • DCC N,N-dicyclohexylcarbodiimide
  • EDC N′-(dimethylaminopropyl)-N-ethylcarbodiimide
  • TBTU O-
  • the activation may be carried out using organic bases such as triethylamine or pyridine, while DMAP (dimethylaminopyridine) may additionally be added.
  • Suitable solvents include DMF, THF, ethyl acetate, toluene, chlorinated hydrocarbons or mixtures thereof.
  • the arylamide (VI) thus obtained in a high yield and high purity is reacted with the corresponding 2-aminoacetaldehyde using suitable organic or inorganic bases in the sense of a Wittig-Horner-Emmons reaction (Diagram 3).
  • This reaction may be carried out directly or after isolation of the compound (VI), for example by precipitation by the addition of tert-butylmethyl ether, for example.
  • Suitable bases include for example DBU (1,5-diazabicyclo[4.3.0]non-5-ene), sodium hydroxide and potassium hydroxide, of which sodium hydroxide and potassium hydroxide are preferred and potassium hydroxide is particularly preferred.
  • a corresponding equivalent e.g. a hydrate or acetal, may be used, from which the aldehyde is released (beforehand or in situ).
  • the acetals used may be for example compounds of the following general type: wherein R 2 to R 5 in each case represent a straight-chain or branched C 1-4 -alkyl group, while the groups may be identical or different.
  • aminocrotonylarylamide of formula (VII) for example 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline of formula (I), may then be converted into the salts thereof, particularly the physiologically acceptable salts thereof, by methods known per se. Preferably they are converted into fumarates, tartrates or maleates.
  • the compound (I) is dissolved in a suitable solvent, such as for example methanol, isopropanol, n-butanol or ethanol, optionally with the addition of water, preferably ethanol, and combined with crystalline maleic acid or a maleic acid solution, with heating.
  • a suitable solvent such as for example methanol, isopropanol, n-butanol or ethanol
  • water preferably ethanol
  • crystalline maleic acid or a maleic acid solution with heating.
  • ethanol ethanol
  • the reaction conditions are preferably selected so that the desired salt crystallises out as quickly as possible.
  • Preferably approx. 2 equivalents of maleic acid are used.
  • the starting compound of formula (V) may for example be prepared as follows in accordance with methods known from the literature.
  • the invention also relates to 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline dimaleate.
  • This salt is particularly suitable for pharmaceutical use as it exists in only one crystalline modification, which is moreover anhydrous and very stable.
  • an active substance not only has to exhibit the desired activity, but must also conform to additional requirements in order to be allowed to be used as a pharmaceutical composition. These parameters are to a large extent connected with the physicochemical nature of the active substance.
  • examples of these parameters are the stability of effect of the starting material under various environmental conditions, stability during production of the pharmaceutical formulation and stability in the final medicament compositions.
  • the pharmaceutically active substance used for preparing the pharmaceutical compositions should therefore have a high stability which must be guaranteed even under various environmental conditions. This is absolutely essential to prevent the use of pharmaceutical compositions which contain, in addition to the actual active substance, breakdown products thereof, for example. In such cases the content of active substance in pharmaceutical formulations might be less than that specified.
  • the absorption of moisture reduces the content of pharmaceutically active substance on account of the weight gain caused by the uptake of water.
  • Pharmaceutical compositions with a tendency to absorb moisture have to be protected from damp during storage, e.g. by the addition of suitable drying agents or by storing the medicament in a damp-proof environment.
  • the uptake of moisture can reduce the content of pharmaceutically active substance during manufacture if the medicament is exposed to the environment without being protected from damp in any way.
  • a pharmaceutically active substance should therefore have only limited hygroscopicity.
  • the solubility of the active substance Another criterion which may be of exceptional importance under certain circumstances depending on the choice of formulation or the choice of manufacturing process is the solubility of the active substance. If for example pharmaceutical solutions are prepared (e.g. for infusions) it is essential that the active substance should be sufficiently soluble in physiologically acceptable solvents. It is also very important for drugs which are to be taken orally that the active substance should be sufficiently soluble.
  • the problem of the present invention is to provide a pharmaceutically active substance which not only is characterised by high pharmacological potency but also satisfies the above-mentioned physicochemical requirements as far as possible.
  • 4-[(3-chloro-4-fluorophenyl)amino]-6- ⁇ [4-(N,N-dimethylamino)-1-oxo-2-buten-1-yl]-amino ⁇ -7-((S)-tetrahydrofuran-3-yloxy)-quinazoline dimaleate has a melting point of 178° C. (cf. the thermoanalysis shown in FIG. 2 ).
  • solution A 58 kg of 1,1-carbonyldiimidazole (22.16 mol) are placed in 12.8 litres of tetrahydrofuran and at 40° C. combined with 4.52 kg (22.16 mol) of diethylphosphonoacetic acid dissolved in 6.5 litres of tetrahydrofuran. The mixture is stirred for 30 minutes at 40° C. The resulting solution is referred to as solution A.
  • solution B 5.6 litres of 30% hydrochloric acid (53.17 mol) are added to 4.4 litres of water. Then 4.28 kg of 95% (dimethylamino)-acetaldehyde-diethylacetal (26.59 mol) are added dropwise within 20 minutes at 30° C. The reaction solution is stirred for 8 hours at 35° C. stirred, cooled to 5° C. and stored under argon. This solution is referred to as solution B.
  • solution C 4.55 kg (68.06 mol) of potassium hydroxide are dissolved in 23.5 litres of water and cooled to ⁇ 5° C. This solution is referred to as solution C.
