Embodiment 1
[0117] Example 1: Preparation of Idelaris Form R
[0118] In a 3L glass bottle, add 200 g of idelaris as an amorphous solid, add 200 ml of dichloromethane, and 50 ml of absolute ethanol, stir mechanically, and heat to reflux at 40°C. After starting to reflux, 1.6 L of acetonitrile was added dropwise, while continuing to raise the temperature to 55°C. The dropwise addition was completed in 5 minutes, and stirring was continued for 30 minutes. Rapid cooling down to 5°C. A large amount of product was precipitated, and the stirring was continued for 1 hour, and the product was obtained by filtration, and the solid was dried in a blast drying oven at 55° C. for 8 hours to obtain 190 g of Idelalis crystal form R, and its X-ray powder diffraction pattern was as follows: figure 1 shown.
Embodiment 2
[0119] Example 2: Preparation of Idelaris Form R
[0120] In a 3L glass bottle, add 200g of idelaris amorphous solid, add 200ml of dichloromethane, 50ml of absolute ethanol, stir magnetically, and heat to 40°C. 2 L of acetonitrile was added dropwise while continuing to raise the temperature to 55°C. The dropwise addition was completed in 5 minutes, and stirring was continued for 30 minutes. Rapid cooling down to 0°C. A large amount of product was precipitated, and the stirring was continued for 1 hour, and the product was obtained by filtration, and the solid was dried in a blast oven at 55° C. for 8 hours to obtain 183 g of idelaris crystal form R, whose X-ray powder diffraction pattern was as follows: figure 2 shown.
Embodiment 3
[0121] Example 3: Preparation of Idelaris Form R
[0122] In a 5L glass bottle, add 500g of idelaris amorphous solid, add 500ml of dichloromethane, 75ml of absolute ethanol, stir mechanically, cool to 0°C, add dropwise 4L of acetonitrile, dropwise add in 10 minutes, continue to Stir at 0°C for 30 minutes. The product was obtained by filtration, and the solid was baked in a blast drying oven at 55°C for 8 hours to obtain 462g of Idelaris crystal form R, and its X-ray powder diffraction pattern was as follows: Figure 9 shown.
