PROCEDURE

实验过程

Imatinib base was suspended in ethanol, methane sulfonic acid was added and heated under reflux for 20 minutes and than filtered at 65° C. The filtrate was evaporated down to 50% and the residue filtered off at 25° C. (filter material A). The mother liquor was evaporated to dryness. The residue and filter material A were suspended in ethanol dissolved under reflux with addition of water. Cooling overnight to 25° C., filtration and drying yielded Imatinib mesylate α-crystal form.
