Example 10

Compound I Form F was obtained via slurry of Compound I calcium salt hydrate Form A in MEK at room temperature.

A. X-Ray Powder Diffraction

XRPD was performed with a Panalytical X'Pert3 Powder XRPD on a Si zero-background holder. The 20 position was calibrated against a Panalytical Si reference standard disc. The XRPD diffractogram for Compound I Form F is shown in FIG. 16 and summarized in Table 21.
