To a suspension of 5-{8-[(3S)-4-acetyl-3-methylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine (56.3 mg, 0.11 mmol) in 10% aqueous ethanol solution (0.5 ml) was added p-toluenesulfonic acid mono hydrate (22.6 mg, 0.12 mmol) at 50° C., and the mixture was cooled down to room temperature, and was then stirred under ice-cooling for 2 hr. The solid precipitated out was collected and dried to give 5-{8-[(3S)-4-acetyl-3-methylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine p-toluenesulfonate (55.1 mg) as a yellow solid.
