Background of the Invention Heteroaromatic fluoroglycosides have been described in EP1 572708 B 1 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- (thfluoromethyl)-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 EP1 572708 B 1 and Published United States Patent Application US 2004/025981 9, has improved properties. Another object is to increase the storage stability of the amorphous heteroaromatic fluoroglycoside from EP1 572708 B 1 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-(thfluoromethyl)-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 Drawings Figure 1: Form A exhibits the XRPD shown. The XRPD was measured in transmission with Cu-K α1 radiation at room temperature. Figure 2 shows the Raman spectrum of Form A . Figure 3 shows the DSC thermogram of Form A . Figure 4 shows the TG analysis of Form A . 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, 3 1 .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.
