Example 23

Compound I calcium salt 1,2-dimethoxyethane solvate Form B was obtained via slurry of Compound I calcium salt hydrate Form A in 1,2-dimethoxyethane 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 calcium salt 1,2-dimethoxy ethane solvate Form B is shown in FIG. 32 and summarized in Table 40.
