[0063] Powder X-ray diffraction analysis was performed using a Bruker AXS D8 Endeavor diffractometer equipped with a copper (Cu) radiation source. The divergence slit was set to 15 mm continuous illumination. Diffracted radiation was detected by a PSD-Lynx Eye detector with the detector PSD aperture set to 2.99 degrees. The X-ray tube voltage and amperage were set to 40 kV and 40 mA, respectively. Data was collected from Cu wavelengths (CuK) from 3.0 to 40.0 degrees 2-theta using a step width of 0.00998 degrees and a step time of 1.0 seconds. α = 1.5418 λ) on a theta-theta goniometer. The anti-scatter screen was set at a fixed distance of 3.0 mm. Samples were rotated at 15 / min during collection. Samples were prepared by placing them in a silicon low background sample holder and rotated during collection. Data was collected using Bruker DIFFRAC Plus software and analysis was performed with EVA diffract plus software. PXRD data files were not processed prior to peak search. Preliminary peak assignments were made using peaks selected at a threshold of 1 using the peak search algorithm in the EVA software. Adjustments were made manually to ensure validity; the output of the automatic assignment was visually confirmed and peak positions were adjusted to the peak maximum. Peaks with a relative intensity of 3% or greater were generally selected. Peaks that were not resolved or matched noise were typically not selected. The typical error associated with peak positions from PXRD as stated in the USP is a maximum of ± 0.2 ° 2θ (USP-941).
[0064] The PXRD pattern of Example 2, free base hemihydrate Form 1, is shown in Figure 1. The PXRD peak list and relative intensity data (2 theta°) for the compound of Example 2, free base hemihydrate Form 1 is provided in Table 1 below:

[0067] [Table 2]
[0068] Solid-state NMR ("ssNMR") analysis was performed using a Bruker-BioSpin Avance III 500 MHz ( 1 The measurements were performed on a cross-polarization magic angle spinning ("CPMAS") probe located within a 1 H frequency NMR spectrometer. The material was a 4 mm ZrO 2 The rotor was tightly packed. A magic angle spinning speed of 14.0 kHz was used. Spectra were collected at ambient temperature (uncontrolled temperature).
[0069] 13 C ssNMR spectra were collected using a proton decoupled CPMAS experiment. A phase-adjusted proton decoupling field of 80-100 kHz was applied during spectral acquisition. The cross-polarization contact time was set to 2 ms and the recycle delay was set to 11.4 s. The number of scans was adjusted to obtain an adequate signal-to-noise ratio. 13 C chemical shift scale, 13 C CPMAS experiments were used and referenced to an external standard of crystalline adamantane, setting its upfield resonance to 29.5 ppm.
[0070] Automated peak picking was performed using Bruker-BioSpin TopSpin version 3.6 software. A threshold of 5% relative intensity was generally used for preliminary peak selection. The output of the automated peak picking was visually checked to ensure validity and manually adjusted if necessary. Although specific solid-state NMR peak values are reported herein, due to differences in instruments, samples, and sample preparation, there is actually a range of these peak values. This is a common practice in the field of solid-state NMR due to the inherent variation in peak positions. 13Typical changes in C chemical shift x-axis values are on the order of plus or minus 0.2 ppm in crystalline solids. Solid-state NMR peak heights reported herein are relative intensities. Solid-state NMR intensities may vary depending on the actual setting of CPMAS experimental parameters and the thermal history of the sample.
[0071] Five characteristic peaks were identified for crystalline (S)-1'-(6-((2-amino-3-chloropyridin-4-yl)thio)-1,2,4-triazin-3-yl)-1,3-dihydrospiro[indene-2,4'-piperidine]-1-amine free base hemihydrate (Form 1): 44.4, 47.7, 149.2, 36.6, and 26.9 ± 0.2 ppm. 13 C chemical shift.

[0074] Raman spectra were collected using a Thermo Scientific iS50 FT-Raman accessory mounted on an FT-IR bench. In the FT-Raman configuration, a CaF2 beam splitter is utilized. The spectrometer is equipped with a 1064 nm diode laser and a room temperature InGaAs detector. Prior to data acquisition, instrument performance and calibration verification was performed using polystyrene. Samples were analyzed in glass NMR tubes as tablets or in a suitable sample holder that held stationary during data collection. Spectra were collected using a laser power between 0.1 and 0.5 W and 512 simultaneous scans. The collection range was 3700-100 cm. -1 The API spectrum was measured using a 2 cm -1Decomposition was used and Happ-Genzel apodization was utilized for all spectra. Multiple spectra were recorded, but the spectra reported are representative of two spots.
[0075] Prior to peak collection, the intensity scale was normalized to 1. Peaks were manually identified using Thermo Nicolet Omnic 9.7.46 software. Peak positions were collected at the peak maximum, but if there was a slope on either side, the peak was only identified as such; peak shoulders were not included. For the solvent-free free base hemihydrate form 1, an absolute threshold of 0.006 with a sensitivity of 75 was utilized during peak collection. Peak positions were rounded to the nearest integer using standard practice (0.5 rounds up, 0.4 rounds down). Peaks with normalized peak intensities between (1-0.75), (0.74-0.30), and (0.29-0) were labeled as strong, medium, and weak, respectively.
