Definitions
- the present invention relates to a new process of synthesis of 7-chloro-4-(piperazin-l- yl)-quinoline, a key intermediate in the synthesis of piperaquine.
- the invention further relates to the crystalline form of said quinoline derivative and to its use in the synthesis of piperaquine itself.
- Piperaquine (l,3-bis-[4-(7-chloroquinolyl-4)-piperazin-l]-propane) of Formula 1 is an anti-malarial product th t belongs to the bisquinoline class of chemical compounds.
- Piperaquine was first synthesized in 1960s (patent US 3173918) and was used in therapy in China and Vietnam. In the last decade it has been object of renewed interest as one of a number of compounds suitable for Artemisinin-based Combination Therapy (ACT).
- ACT Artemisinin-based Combination Therapy
- Eurartesim® contains a fixed-ratio drug combination between piperaquine phosphate and dihydroartemisinin to treat uncomplicated P. falciparum malaria. Since piperaquine presents an extremely long half-life, its combination is expected to be effective both in treating clinical malaria and in giving protection from re-infection.
- Singh T., et al. reported a synthesis of 7-chloro-4-(piperazin-l-yl)-quinoline involving a 10M excess of piperazine, the reaction being conducted at reflux in ethoxyethanol for 24 h.
- the work-up involved basification by means of NaOH and a crystallization from cyclohexane (Singh T., et al., J. Med. Chem., 1971, 14, 4, 283).
- the toxicity of this solvent renders this synthesis rather inadequate. Vennerstrom J.L., et al.
- Liu Y., et al. reported lately a further synthesis of 7-chloro-4-(piperazin-l-yl)- quinoline involving highly diluted conditions in N-methyl-2-pyrrolidinone and a workup by means of dichloromethane to afford the desired compound in 54% yield (Liu Y., et al, Molecules, 2008, 13, 2426).
- WO04002960 reported a 65% yielding synthesis of 7-chloro-4-(piperazin-l-yl)- quinoline which made use of ten equivalents of piperazine and high ethanolic dilution conditions, the reaction being conducted in sealed-tube.
- WO09050734 reported a synthesis wherein 7-chloro-4-(piperazin-l-yl)-quinoline was prepared in 82 to 86% yield from heating to reflux in i-PrOH a 3/1 mixture of piperazine and 4,7-dichloroquinoline in the presence of potassium carbonate.
- Such a process further involved extraction of the aqueous phase with CH 2 CI 2 in order to remove the dimer impurity, and subsequent basification of the aqueous phase with liquor ammonia prior to a second extraction with CH2CI2. After removal of the solvent, the residue was taken-up in hexane to obtain 7-chloro-4-(piperazin-l-yl)-quinoline in 98.56% purity.
- the present invention provides a new "green" process of synthesis of a polymorph of 7- chloro-4-(piperazin-l-yl)-quinoline and the use of the latter in the synthesis of piperaquine or one of its pharmaceutically acceptable salts.
- Said obtained quinoline compound is substantially pure of any impurities.
- the synthesis object of the present invention allows the production of the compound of Formula I the latter being free of any traces of compounds of formula 2 and of any substantial traces of non reacted piperazine.
- the synthesis object of the present invention is environment-friendly (green) and easily feasible in large scale conditions and represents a major improvement over the existing syntheses. It is a highly efficient and cost effective way of synthesising Formula I compound.
- An embodiment of this invention consists of a process to synthesize the compound of Formula I, by reacting 4,7-dichloroquinoline and piperazine in a methanolic solution. In a preferred embodiment, less than three stoichiometric equivalents of piperazine are added.
- reaction mixture is filtered after 8 hours of reflux in methanol.
- the compound of Formula I is obtained highly pure by crystallization.
- the crystallization process involves the use of water.
- 7-chloro-4-(piperazin-l-yl)-quinoline is obtained in a specific polymorphic Form.
- polymorphic Forms B, C, and D are preferred.
- polymorphic Form B is especially preferred.
- washing and any derived word, reflect that water is the ingredient involved in the process of washing.
- substantially pure means that the purity of the compound it refers to is equal to or higher than 99%.
- crystalline Form B of 7-chloro-4-(piperazin-l-yl)-quinoline is obtained.
- crystalline Form D of 7-chloro-4- (piperazin-l-yl)-quinoline is obtained.
- Figure 1 represents the X-ray spectra of 7-chloro-4-(piperazin-l-yl)-quinoline Form A polymorph.
- Figure 2 represents the X-ray spectra of 7-chloro-4-(piperazin-l-yl)-quinoline Form B polymorph.
- Figure 3 represents the X-ray spectra of 7-chloro-4-(piperazin-l-yl)-quinoline Form C polymorph.
- Figure 4 represents the X-ray spectra of 7-chloro-4-(piperazin-l-yl)-quinoline Form D polymorph.
- Figure 5 represents the X-ray spectra of 7-chloro-4-(piperazin-l-yl)-quinoline Form E polymorph.
- Figure 6 table showing all the peaks of the X- diffraction spectra of the five polymeric forms.
- Piperazine impurity starting material content was determined to be less than 30 ppm.
- X-Ray characterization It will be understood by those skilled in the art that the 2-theta values of the X-ray powder diffraction pattern may differ slightly from one machine to another or from one sample to another, and therefore the values mentioned are not to be interpreted as absolute.
- a still further embodiment of the present invention is directed to a crystal form of 7-chloro-4-(piperazin-l-yl)-quinoline that presents a X-ray powder diffraction pattern substantially the same as the X-ray powder diffraction pattern shown in Figure 1.
- the crystalline solid obtained in example 1 was dried in a dessicator at RT in the presence of silica gel for 24 hours to obtain crystalline 7-chloro-4-(piperazin-l-yl)- quinoline Form A.
