A solution of 4-[1-(1-cyclopentylbut-3-yn-1-yl)-1H-pyrazol-4-yl]-7-[2-(trimethylsilyl)-ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidine (52 mg, 0.12 mmol) in DCM (3 mL) and TFA (1 mL) was stirred for 2 hours. The solvents were removed in vacuo. The resulting residue was dissolved in THF (3 mL) and 6N NaOH (2 mL) was added. After stirring for 1 hour, the mixture was partitioned between water and ethyl acetate. The organic layer was dried over sodium sulfate and the solvent was removed in vacuo. Purification via preparative-HPLC/MS (C18 eluting with a gradient of H2O and ACN containing 0.1% TFA) afforded product (30 mg, 60%).
