Reaction Steps

To a suspension of 5-{8-[(3R)-4-acetyl-3-methylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine (101 mg, 0.194 mmol) in 10% aqueous ethanol solution (2 ml) was added 98% sulfuric acid (0.012 mL, 0.213 mmol) at room temperature, and the mixture was stirred for 30 minutes. The insoluble solid was collected and dried to give 5-{8-[(3R)-4-acetyl-3-methylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine sulfate (89 mg) as a yellow solid.
