실험 절차

The solution of imatinib mesylate and isopropanol is prepared by a process comprising: providing a suspension of imatinib base and isopropanol containing up to 7% by weight of water; admixing the suspension with cooled methanesulfonic acid; and maintaining the mixture at the cooled temperature to obtain a solution of imatinib mesylate. Preferably, the suspension of imatinib base is prepared by suspending imatinib base in isopropanol containing up to 7% by weight of water at a temperature of about −10° C. to about −5° C., more preferably, at a temperature of about −10° C. Preferably, the isopropanol contains up to 5% of water by weight. Preferably, methanesulfonic acid is added to the suspension at a temperature of about 0° C. to about −10° C., more preferably at a temperature of about −10° C., most preferably in a stoichiometric amount. Preferably, the solution is maintained at a temperature of about 0° C. to about −20° C., more preferably, at a temperature of about −15° C. Preferably, the solution is maintained for a period of about 10 hours to about 24 hours, more preferably for about 12 hours to about 16 hours, most preferably about 12 hours.
