Hydroxybenzenesulfonic acid → 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 benzenesulfonate

Participants

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 (126 mg, 0.242 mmol) in 10% aqueous ethanol solution (5 ml) was added benzenesulfonic acid mono hydrate (46.8 mg, 0.266 mmol) at 50° C., and the mixture was allowed to be cooled down to room temperature, and stirred for 15 hr. The solid precipitated out 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 benzenesulfonate (110 mg) as a yellow solid.
