Claims (22)

1. A crystalline Compound (I):

which has an X-ray powder diffraction pattern comprising peaks at approximately 18.1, 20.3, 22.9, 24.0, and 26.3±0.2°2θ;

wherein the crystalline Compound (I) is anhydrous and unsolvated; and

comprises less than 10% by weight of any other amorphous or crystalline forms of Compound (I).

2. The crystalline Compound (I) of claim 1 , comprising less than 5% by weight of any other amorphous or crystalline form of Compound (I).

3. The crystalline Compound (I) of claim 2 , wherein the crystalline compound comprises less than 100 ppm of a compound of Formula (II),

as determined by GC/MS.

4. The crystalline Compound (I) of claim 3 , wherein the crystalline compound comprises less than 50 ppm of a compound of Formula (II).

5. The crystalline Compound (I) of claim 4 , wherein the crystalline compound comprises less than 10 ppm of a compound of Formula (II).
