Procedure

To a solution of methyl 4-{[7-({3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}amino)-1H-pyrazolo[4,3-d]pyrimidin-1-yl]methyl}benzoate (25 mg) in a mixed solvent of tetrahydrofuran/methanol (1:1, 1 mL) was added 1N aqueous sodium hydroxide solution (0.5 mL), and the mixture was stirred at room temperature for 1 hr. After the completion of the reaction, 1N aqueous hydrochloric acid solution (0.5 mL) and water (1 mL) were added under ice-cooling, and the mixture was stirred at room temperature for 1 hr. The resultant solid was collected by filtration, and washed with diisopropyl ether and dried to give the title compound (16 mg) as pale-yellow crystals.
