Toluene → 4-(4-methanesulfonyl-phenoxy)-1H-pyrazolo[3,4-d]pyrimidine

Participants

Reaction Steps

Triethylsilane (150 μL, 0.94 mmol) was added to a solution of 4-(4-methanesulfonyl-phenoxy)-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-d]pyrimidine (150 mg, 0.4 mmol) in dichloromethane (3 mL). A solution of trifluoroacetic acid (1 mL) in dichloromethane (3 mL) was added dropwise and then the reaction mixture was stirred for 1 h. Toluene (2 mL) was added and the volatiles were evaporated. The residue was purified by column chromatography, eluting with 0-5% methanol/ethyl acetate to give 4-(4-methanesulfonyl-phenoxy)-1H-pyrazolo[3,4-d]pyrimidine (71 mg, 61%) as a white solid.
