Procedure

A solution of -(3-(benzyloxy)-5-fluorophenyl)-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (15 mg, 0.04 mmol) in MeOH (0.9 mL) was flushed with argon. Pd on activated carbon (10 mL) was carefully added while keeping reaction under an argon atmosphere. Reaction was flushed with H2 gas and left under H2 atmosphere overnight at room temperature. The reaction was filtered through celite and rinsed with MeOH to yield BA22 (15 mg, 100% yield). ESI-MS (M+H)+ m/z calcd 288.1, found 288.1.
