Definitions

  • the invention relates to a new production and purification method of polymorphs and solvates of dasatinib.
  • Dasatinib N-(2-chloro-6-methylphenyl)-2-[[6-[4-(2-hydroxyethyl)- 1 -piperazinyl]-2- methyl-4-pyrimidmyl]amino]-5-thiazole carboxamide of formula I, also known as BMS- 354825, is a cancer treatment drug developed by Bristol-Myers Squibb and sold under the trade name Sprycel®.
  • Dasatinib is a multi- BCR/ABL and Src family tyrosine kinase inhibitor and it is used for treatment of chronic myelogenous leukaemia (CML) as a secondary drug after primary treatment with imatinib (Gleevec®).
  • CML chronic myelogenous leukaemia
  • dasatinib is prepared by reaction of the key intermediate of formula II with l-(2-hydroxyethyl)piperazine in the presence of a base and a suitable solvent (Scheme 1).
  • a similar preparation method was later used in a number of other process patents, only varying the corresponding base or solvent.
  • a suitable solvent or procedure Through the selection of a suitable solvent or procedure a great number of solvates or polymorphs can be prepared.
  • Polymorphs have been one of the most frequently studied physical characteristics of active pharmaceutical substances (API) recently. Thus, different polymorphs of one API may have entirely different physical-chemical properties such as solubility, melting point, mechanical resistance of crystals but they may also influence the chemical and physical stability.
  • the process patent WO2005077945A2 describes preparation of the following solvates of dasatinib: monohydrate, butanol solvate, as well as two anhydrous forms (N-6 and T1H1- 7).
  • a related patent also mentions two ethanol solvates, the hemi-ethanol and diethanol solvates (US 8 242 270 B2). Salts, various combinations of salts and their solvates have been described in detail in the patent application WO2007035874A1.
  • API solvates or salts are used in drug formulations in many cases.
  • the limits for individual solvents their contents or maximum daily doses have to be strictly observed. Then, these limits can dramatically restrict their effective use.
  • the clearly most convenient option is the use of sufficiently stable polymorphs of API that do not contain any solvents bound in the crystalline structure.
  • N-6 a stable anhydrous form of dasatinib
  • the main disadvantages of the preparation of N-6 is the necessity of desolvation of the solvated form of the API at high temperatures (WO2009053854A2), or application of an increased temperature (50°C and more) and vacuum for a relatively long time (8-12h; WO2010139981A2 and WO2005077945A2).
  • These procedures are very demanding from the point of view of general technology, energy and time, to say nothing of the necessity to work under an inert atmosphere to prevent possible oxidation-degradation reactions of the API.
  • dasatinib may be oxidized by atmospheric oxygen to the corresponding N-oxide (oxidation occurs in the piperazine ring), which may undergo the Cope elimination at increased temperatures. This secondary reaction may subsequently impair the purity of the prepared API.
  • the invention relates to a method for the preparation of dasatinib of formula I in the anhydrous form N-6, characterized by the following reflections in an X-ray powder diffraction pattern, measured using the CuKa radiation: 6.8; 12.3; 13.2; 13.8; 16.7; 21.0; 24.3 and 24.8 ⁇ 0.2° 2-theta
  • the preparation method in accordance with the invention is based on the surprising finding that the anhydrous polymorph of dasatinib N-6 can be obtained by re-crystallization of any form of dasatinib from a mixture of a suitable solvent and a suitable co-solvent.
  • This new preparation method of the anhydrous polymorph N-6 differs from the hitherto known procedures by excellent repeatability and, above all, simple execution. Intensive drying (at a high temperature, for a long time, in vacuo) is no longer required and the product aspirated directly after crystallization corresponds, according to the XRPD pattern, to the polymorph N- 6 as described in literature.
  • Dasatinib of formula I is prepared by a reaction of the intermediate of formula II with l-(2- hydroxyethyl)piperazine in the presence of diisopropylethylamine (DIPEA) in an organic solvent from the group of dipolar aprotic solvents, higher alcohols or diols.
  • DIPEA diisopropylethylamine
  • a dipolar aprotic solvent from the group of N-methyl-2-pyrrolidone (NMP), N ⁇ iV-dimethyl formamide (DMF), AyV-dimethyl acetamide (DMA), dimethyl sulfoxide (DMSO), formamide (FA), N,N -dimethyl propylene urea (DMPU) and l,3-dimethyl-2-imidazolidinone (DMI) is used, the reaction is carried out at 50-110°C under an inert atmosphere for 1/2-6 hours. In a preferable embodiment, NMP, DMSO, DMPU or DMI is used and the reaction is carried out at 90°C for 1-3 hours.
