Reaction Steps

A solution of 4-[1-(1-cyclopentyl-4,4-difluorobut-3-en-1-yl)-1H-pyrazol-4-yl]-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidine (41 mg, 0.086 mmol) in DCM (3 mL) and TFA (1.5 mL) was stirred for two hours at room temperature. The solution was then concentrated in vacuo. The resulting residue was redissolved 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 the desired product (39 mg, 98%).
