Procedure

To a solution of butyl 1-(2-(4-(4-acetylpiperazin-1-yl)phenylamino)-9H-purin-6-yl)piperidine-3-carboxylate (76 mg, 0.15 mmol) in THF (2 mL), aq. 1N LiOH (1.00 mL, 1.00 mmol) was added. The mixture was stirred at room temperature for 68 h. HOAc (1 mL) was added to neutralize LiOH. The mixture was then purified by HPLC to give 1-(2-(4-(4-acetylpiperazin-1-yl)phenylamino)-9H-purin-6-yl)piperidine-3-carboxylic acid (45 mg), MS 465.3 (M+H); UV 205.8, 272.8 nm; and 1-(2-(4-(piperazin-1-yl)phenylamino)-9H-purin-6-yl)piperidine-3-carboxylic acid (8 mg), MS 423.3 (M+H).
