Embodiment 1
[0101] Preparation of brigatinib crystal form LX-1
[0102] Dissolve brigatinib 50mg in 250μl methanol at 70°C. Add 250 μl n-butyl acetate and 750 μl n-heptane at room temperature. Place it in a freezer at -20°C to volatilize to obtain a solid powder. It was detected as the crystal form LX-1. Its XRPD spectrum is attached figure 1 , DSC spectrum see attached figure 2 , TGA spectrum see attached image 3 .
[0103] From figure 1 It can be seen that the X-ray powder diffraction pattern of brigatinib crystal form LX-1 represented by 2θ angle is at 5.4±0.2°, 10.4±0.2°, 10.8±0.2°, 11.1±0.2°, 12.9±0.2°, 14.9 Available at ±0.2°, 15.9±0.2°, 17.2±0.2°, 17.8±0.2°, 19.2±0.2°, 20.2±0.2°, 20.6±0.2°, 22.0±0.2°, 24.0±0.2° and 25.6±0.2° Diffraction peaks. The specific X-ray powder diffraction data are shown in the table below.
[0104] Numbering 2θ angle (°) Relative Strength(%) Numbering 2θ angle (°) Relative Strength(%) 1 5.4 63.3 17 21.7 18.3 2 ...
Embodiment 2
[0107] Preparation of brigatinib crystal form LX-1
[0108] Dissolve brigatinib 200mg in 1ml methanol at 70°C. Add 1ml of n-butyl acetate at room temperature, and add 3ml of n-heptane. Place it in a freezer at -20°C to volatilize to obtain a solid powder. It was detected as the crystal form LX-1. The solid-state characterization data are the same as in Example 1.
Embodiment 3
[0110] Preparation of brigatinib crystal form LX-1
[0111] Dissolve brigatinib 200mg in 2ml methanol at 70°C. 2 ml of ethyl acetate was added at room temperature, and 5 ml of cyclohexane was added. Place it in a freezer at -25°C to volatilize to obtain a solid powder. It was detected as the crystal form LX-1. The solid-state characterization data are the same as in Example 1.
