Procedure

To a solution of 3-(2-(4-(4-acetylpiperazin-1-yl)phenylamino)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)benzamide (40 mg, 0.064 mmol) in MeOH (3 mL), aq. 1N KOH (1.0 mL, 1.0 mmol) was added. The mixture was heated at 60° C. for 3 h. It was concentrated in vacuo. The residue was acidified with HOAc (1 mL) before being purified by HPLC to give 3-(2-(4-(4-acetylpiperazin-1-yl)phenylamino)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)benzamide (15 mg), MS 471.1 (M+H); UV 207.3, 284.1, 311.5 nm; and 3-(2-(4-(piperazin-1-yl)phenylamino)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)benzamide (5 mg), MS 429.1 (M+H); UV 202.6, 279.3 nm.
