Reaction Steps

X-ray powder diffraction (XRPD) analysis of the monomesylate (MSA) and succinate forms of the compound of Example 2 herein were conducted on a diffractometer (PANanalytical XPERT-PRO, PANalytical B.V., Almelo, Netherlands) using copper radiation (Cu Kα, λ=1.5418 Å). Samples were prepared for analysis by depositing the powdered sample in the center of an aluminum holder equipped with a zero background plate. The generator was operated at a voltage of 45 kV and amperage of 40 mA. Slits used were Soller 0.02 rad., antiscatter 1.0°, and divergence. The sample rotation speed was 2 sec. Scans were performed from 2 to 40° 2-theta. Data analysis was performed by X'Pert Highscore version 2.2c (PANalytical B.V., Almelo, Netherlands) and X'Pert data viewer version 1.2d (PANalytical B.V., Almelo, Netherlands). The XRPD patterns for Mono MSA Forms I & II were obtained using the instrument setting as follows: 45 KV, 40 mA, Cu Kα, λ=1.5418 Å, scan range 2.-40°, step size 0.0167°, counting time: 15.875 s. The XRPD patterns for Succinate Forms I & II were obtained using the instrument setting as follows: 45 KV, 40 mA, Cu Kα, λ=1.5418 Å, scan range 2.-40°, step size 0.0084°, counting time: 95.250 s.
