Description

A novel crystalline heteroaromatic fluoroglycoside hydrate, processes for making, methods of use and pharmaceutical compositions thereof

Field of the Invention

The invention relates to a crystalline hydrate of a heteroaromatic fluoroglycoside known as 4-[(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy- 4-fluoro-beta-D-glucopyranoside.

Background of the Invention

Heteroaromatic fluoroglycosides have been described in EP1572708 B1 and Published United States Patent Application US 2004/0259819. The aforementioned patent and/or application makes no mention as to the particular physical form of 4-[(4- methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D- glucopyranoside provided from the procedure disclosed therein or the hydration state or physical purity of the compound provided from the procedure. Furthermore, there is no physical chemical data reported for 4-[(4-methoxyphenyl)methyl]-5- (trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D-glucopyranoside in said published patent/application that suggests the physical form of the product obtained. It is an object of the invention to provide a stable hydrate of said compound.

It is an object of the invention to provide a heteroaromatic fluoroglycoside which, compared to that described in EP1572708 B1 and Published United States Patent

Application US 2004/0259819, has improved properties. Another object is to increase the storage stability of the amorphous heteroaromatic fluoroglycoside from EP1572708 B1 which is a crucial parameter for formulating pharmaceuticals. Another object is to provide processes for the preparation of a stable monohydrate form of 4- [(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta- D-glucopyranoside or a tautomer thereof (henceforth referred to as "Form A"). The object is achieved by providing a stable crystalline hydrate of the formula I

in which n has a value of from 0.9 to 1.1 or a tautomer thereof.

Although widespread, not all pharmaceutically active compounds form hydrates or solvates. The existence of hydrates, their crystal structure and properties are unpredictable.

Preference is given to the crystalline hydrate of the compound of the formula I or a tautomer thereof in which n has a value of 1.

Detailed Description of the Invention

By providing a crystalline hydrate of formula I (or more specifically, Form A) according to the invention, the active ingredient

- is easier to purify (for example by recrystallization)

- can have a defined purity required for the approval of a pharmaceutical - is readily detectable and identifiable by customary methods such as XRPD (X- ray powder diffraction), melting point, IR (infrared spectrum), and it has

- has a reproducible and stable physical quality.

Crystalline active ingredients are generally more stable than amorphous active ingredients. Problems with the degradation of the active ingredients and the degradation products formed are thus avoided. The amorphous form of an active ingredient may also comprise an unwanted content of solvents. These are generally difficult to remove, since recrystallization is not possible.

The amorphous form is a more energetic state than a crystalline form and, as such, is more difficult to stabilize. Molecules of an amorphous material may spontaneously rearrange to a lower energy crystalline one leading to a change in activity of the active ingredient. As a consequence there may be significant effect on the reliability of the active ingredient and thus a risk for the patient. It is also difficult to prove that different batches of amorphous active ingredient are identical.

A further embodiment of the invention comprises Form A wherein the XRPD, measured with CuKa radiation, has a main peak of 20.27 degrees 2 theta ± 0.2 degrees 2 theta. A further embodiment of the invention comprises Form A wherein the XRPD, measured with CuKa radiation, has at least peaks of the following 2 theta values: 14.88, 20.27, 22.98 ± 0.2 degrees 2 theta.

A further embodiment of the invention comprises Form A wherein the XRPD, measured with CuKa radiation, has at least peaks of the following 2 theta values: 5.98, 14.88, 20.27, 22.98, 26.52 ± 0.2 degrees 2 theta.

A further embodiment of the invention comprises Form A wherein the XRPD, measured with CuKa radiation, has at least peaks of the following 2 theta values: 5.98, 7.48, 12.09, 14.88, 14.99, 20.27, 20.75, 22.81 , 22.98, 26.52, 27.60, 31.01 ± 0.2 degrees 2 theta.

Formulations

The amount of a compound of formula I necessary to achieve the desired biological effect depends on a number of factors, for example the specific compound chosen, the intended use, the mode of administration and the clinical condition of the patient. The daily dose is generally in the range from 0.01 mg to 100 mg (typically from 0.05 mg and 50 mg) per day and per kilogram of body weight, for example 0.05-10 mg/kg/day.

Single-dose formulations which can be administered orally, such as, for example, tablets or capsules may contain, for example, from 1.0 to 1000 mg, typically from 5 from 600 mg. For the therapy of the abovementioned conditions, the compounds of formula I may be used as the compound itself, but they are preferably in the form of a pharmaceutical composition with an acceptable carrier. The carrier must, of course, be acceptable in the sense that it is compatible with the other ingredients of the composition and is not harmful for the patient's health. The carrier may be a solid or a liquid or both and is preferably formulated with the compound as a single dose, for example as a tablet, which may contain from 0.05% to 95% by weight of the active ingredient. Other pharmaceutically active substances may likewise be present, including further compounds of the formula I. The pharmaceutical compositions of the invention can be produced by one of the known pharmaceutical methods, which essentially consist of mixing the ingredients with pharmacologically acceptable carriers and/or excipients.

Pharmaceutical compositions of the invention are those suitable for oral and peroral (for example sublingual) administration, although the most suitable mode of administration depends in each individual case on the nature and severity of the condition to be treated and on the nature of the compound of formula I used in each case. Coated formulations and coated slow-release formulations also belong within the framework of the invention. Acid- and gastric juice-resistant formulations are possible. Suitable coatings resistant to gastric juice comprise cellulose acetate phthalate, polyvinyl acetate phthalate, hydroxypropylmethylcellulose phthalate and anionic polymers of methacrylic acid and methyl methacrylate.

Suitable pharmaceutical compounds for oral administration may be in the form of separate units such as, for example, capsules, cachets, suckable tablets or tablets, each of which contains a defined amount of the compound of formula I; as powders or granules; as solution or suspension in an aqueous or nonaqueous liquid; or as an oil- in-water or water-in-oil emulsion. These compositions may, as already mentioned, be prepared by any suitable pharmaceutical method which includes a step in which the active ingredient and the carrier (which may consist of one or more additional ingredients) are brought into contact. The compositions are generally produced by uniform and homogeneous mixing of the active ingredient with a liquid and/or finely divided solid carrier, after which the product is shaped if necessary. Thus, for example, a tablet can be produced by compressing or molding a powder or granules of the compound, where appropriate with one or more additional ingredients. Compressed tablets can be produced by tableting the compound in free-flowing form such as, for example, a powder or granules, where appropriate mixed with a binder, glidant, inert diluent and/or one (or more) surface-active/dispersing agent(s) in a suitable machine. Molded tablets can be produced by molding the compound, which is in powder form and is moistened with an inert liquid diluent, in a suitable machine. Pharmaceutical compositions which are suitable for peroral (sublingual) administration comprise suckable tablets which contain a compound of formula I with a flavoring, normally sucrose and gum arabic or tragacanth, and pastilles which comprise the compound in an inert base such as gelatin and glycerol or sucrose and gum arabic.

Combination with other active ingredients

The compound(s) of the invention (I) can also be administered in combination with further active ingredients.

Further active ingredients suitable for combination products are: All antidiabetics which are mentioned in the Rote Liste 2007, chapter 12; all weight- reducing agents/appetite suppressants which are mentioned in the Rote Liste 2005, chapter 1 ; all lipid-lowering agents which are mentioned in the Rote Liste 2007, chapter 58. They may be combined with the compound of the invention of the formula I in particular for a synergistic improvement in the effect. The active ingredient combination can be administered either by separate administration of the active ingredients to the patient or in the form of combination products in which a plurality of active ingredients is present in a pharmaceutical preparation.

"Essentially pure" means the starting material has an HPLC purity grade of at least 98%. The HPLC purity grade for the starting material is preferably at least 99.8%.

The experiments described herein comprise thermodynamically controlled crystallization of essentially pure 4-[(4-methoxyphenyl)methyl]-5-

(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D-glucopyranoside by varying solvent and cooling rate and also by adding anti-solvents. The particular forms may also be produced through maturation procedures and/or dehydration of hydrates followed by rehydration.

Crystallization from a solution of essentially pure 4-[(4-methoxyphenyl)methyl]- 5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D- glucopyranoside(anhydrate or hydrate) in isopropanol/water mixture containing about 1 .9 equivalents of KOAc/HOAc (pH about 6) produces Form A.

Form A is isolated by dissolving an essentially pure hydrate of 4-[(4- methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro- beta-D-glucopyranoside in isopropyl acetate and adding an anti solvent such as n-heptane. Alternative antisolvents such as methylcyclohexane may also be used.

Form A may be isolated from an aqueous solution of a salt of 4-[(4- methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]4-deoxy-4-fluoro- beta-D-glucopyranoside. For example, a sodium salt of the pyrazole functionality, or other suitable salt of the pyrazole may be used to prepare the aqueous solution. The pH is adjusted and the free acid is extracted into an organic solvent, preferably isopropyl acetate. Addition of an antisolvent such as, for example, n-heptane crystallizes 4-[(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4- deoxy-4-fluoro-beta-D-glucopyranosidehydrate i.e. Form A. Alternative antisolvents such as methylcyclohexane may also be used.

In addition, Form A can be obtained after completely or substantially dehydrating solid essentially pure 4-[(4-methoxyphenyl)methyl]-5- (trifluoromethyl)-1 H-pyrazole-3-yl]i4-deoxy-4-fluoro-beta-D-glucopyranoside hydrate by drying by heating followed by a rehydration process of the resultant solid in a humid environment (relative humidity: 20-90%).

Form A may be maintained during drying of wet 4-[(4-methoxyphenyl)methyl]-5- (trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D- glucopyranosidemonohydrate by avoiding dehydration, for example by drying under a humid environment (relative humidity 20-90%).

The following examples detailed below are provided to more specifically describe and to better teach how to make and practice the claimed compounds of the present invention and methods for their preparation. The examples are provided for illustrative purposes only and it is to be recognized that not all embodiments of the invention can be disclosed in this manner. Therefore, the examples are to be construed in this way and should not be interpreted as limiting the spirit and scope of the invention as later recited by the claims that follow.

EXAMPLES

Unless otherwise specified, the experiments specifically disclosed herein were carried out using a hydrated compound of the formula Il

wherein the HPLC purity grade of the compound is at least 99.8 %.

Crystallisation by adding antisolvent at room temperature

Form A was precipitated from different solvents at room temperature by adding n- heptane or diisopropylether as antisolvent.

Example 1a: 0.209 g of compound of the formula Il was dissolved in 12.45 mL of ethanol. The slightly turbid solution was stirred overnight. 75mL of diisopropylether were added to the stirred solution. Since no precipitation appeared, the sample was evaporated at room temperature.

Crystallisation by evaporation of the solvent at elevated temperatures

The compound of the formula Il was dissolved at elevated temperatures in several solvents and the solvents were then allowed to evaporate from the stirred solutions. Example 1 b: 0.212 g of compound of the formula Il was dissolved in 2.50 ml_ of water/methanol 1 :1 (vol/vol) at about 65°C. The solvent was allowed to evaporate from the stirred solution at the same temperature overnight.

Other crystallisation methods

Samples of the compound of formula Il were dissolved at 65°C in several solvents and transferred to 0ºC environment in which they were stirred for 0.5, 19 or 24 hours before vacuum filtration.

Example 1 c: Rapid cooling of a stirred solution (slightly turbid) of 0.220 g of compound of formula Il in 8.0 ml_ butyl acetate from 65°C to 0ºC. Since no precipitation occurred the sample was evaporated at room temperature.

Example 1d: Rapid cooling of a stirred solution (slightly turbid)) of 0.224 g of compound of formula Il in 13.0 ml_ ethanol from 65°C to 0ºC. Since no precipitation occurred the sample was evaporated at room temperature.

Example 1 e: Rapid cooling of a stirred solution (slightly turbid)) of 0.210 g of compound of formula Il in 1.0 ml_ methyl ethyl ketone from 65°C to 0ºC. Since no precipitation occurred, the sample was evaporated at room temperature.

Example 1f: Preparation of Form A

4-[(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4- fluoro-beta-D-glucopyranosidemonohydrate (25.50kg) and potassium acetate (10.40kg) were charged to a reactor and a nitrogen atmosphere was established. n-Propanol (61 kg) and demineralized water (74kg) were added and the temperature adjusted to 22±3°C. Acetic acid (3.30kg) was then added maintaining the batch temperature at 22±3°C and was followed by a rinse of the charging line with demineralized water (2.6kg). The mixture was stirred at 22±3°C for not less than 15 minutes and visually checked for complete dissolution. The batch was then transferred to a second reactor through a polishing filter fitted with a 0.45μm cartridge and the first reactor was rinsed with n-propanol (20kg) and demineralized water (25.5kg). The rinses were charged to this second reactor and the mixture was heated to 45±3°C. Demineralized water (281 kg) was added at a controlled rate maintaining the batch temperature at 42±5°C. The resultant solution was cooled to 29±1 °C and then gradually to 22±1 °C using a jacket cooling profile (4.5°C/hr). The resulting slurry was heated to 36±2°C and maintained at 36±2°C for not less than 80 minutes. The batch was then cooled to 1 ±3°C using a jacket cooling profile (3°C/hr) and held for not less than 1 hour at 1 ±3°C. The batch was filtered, washed twice with demineralized water (2 X 160kg), dried under reduced pressure (<100mm Hg) at 60±5°C such that water content was less than 3.0% by KF titration and then allowed to rehydrate to give the product 4- [(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4- fluoro-beta-D-glucopyranosideas the monohydrate form A (22.95kg; molar yield 90.0%).

Example 1g: Preparation of Form A

4-[(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4- fluoro-beta-D-glucopyranosidemonohydrate (1 1 .70kg) and isopropyl acetate (68.0kg) were charged to a reactor. The mixture was stirred at 45±3°C until all the solids dissolved. The solution was cooled down to 22±3°C and transferred to a second reactor through a polishing filter fitted with a 0.8μm cartridge. The temperature of the batch was adjusted to 55±3°C and n-heptane (54.0kg) were added maintaining a batch temperature of 55±3°C. The solution was cooled to 0±2°C over a period of 3.5 hours, filtered, washed with n-heptane (27.0kg) and dried under reduced pressure (<100mm Hg) at a temperature of not more than 50ºC such that residual solvent levels for isopropyl acetate and n-heptane were less than 5000 ppm each. The solids were then allowed to rehydrate under humid conditions to give the product 4-[(4-methoxyphenyl)methyl]-5- (trifluoromethyl)-1 H-pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D-glucopyranoside as the monohydrate form A (10.90kg; molar yield 93.2%).

Example 1 h: Preparation of Form A through solid state dehydration/rehydration

A 24.8439g sample of 4-[(4-methoxyphenyl)methyl]-5-(trifluoromethyl)-1 H- pyrazole-3-yl]-4-deoxy-4-fluoro-beta-D-glucopyranoside(a mixture of crystalline hydrates) was transferred into an open crystallization dish to form an 3 cm thick layer. The dish was placed in an open aluminum dessicator and transferred to a vacuum oven. The sample was dried at 60ºC under vacuum for 24 hours. The sample was then placed on an analytical balance in the presence of an open vessel containing water and allowed to rehydrate. The weight stabilized at 1 molar equivalent of water and analytical studies confirmed the sample as form A.

Form A was characterized by the following methods:

X-ray powder diffraction experiments (XRPD) were performed with a STOE Stadi-P transmission diffractometer using Cu-Kcci radiation. For room temperature powder diffraction, linear position sensitive detectors were used. Dry samples were investigated in a flat preparation. The measured data was evaluated and plotted with the software WinXPOW v2.12.

All DSC measurements were performed with a METTLER DSC822e (module DSC822e/700/109/414935/0025). If not indicated differently, 40μl_ Al-crucibles with sealed lid and hole were used. All measurements were carried out in a nitrogen gas flow of 50 mL/min and typical heating rates range from 1 to 507min. The measured data was evaluated via the software provided with said instrument.

The thermogravimetric analyses were performed with a METTLER TGA85 1 e (module TGAISDTA85 1 elSF 1 1001042). Open 100μL Al-crucibles were used and the measurements were performed in a nitrogen gas flow of 50 mL/min. The measured data was evaluated via the software STARe V8.10.

Infra-red absorption spectra were recorded on a FT-IR Spectrometer (Nexus 470, NICOLET). The spectra are evaluated and plotted by the software Omnic V. 6.1 A.

Raman spectra were recorded with an FT-Raman spectrometer (RFS-1 OOIS, BRUKER) equipped with a 1 .5 W NIR-Laser (Nd:YAG; h=1064 nm) and a nitrogen-cooled D4 1 8-T NIR-Detector. The spectra are evaluated and plotted by the software OPUS V. 4.2.

Form A exhibits the XRPD shown in Figure 1. The XRPD was measured in transmission with Cu-Kalpha1 radiation at room temperature. The most important 2 theta values are summarized in table 1.

Owing to natural deviations in the samples or in the measuring method, the 2 theta values of the peaks can be stated with an accuracy of +/- 0.2 degrees theta.
