Reaction Steps

4-(1-Benzyl-azetidin-3-yloxy)-1-(4-methanesulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidine (0.01 mmol, 46 mg) was dissolved in a mixture of ethyl acetate (5 mL) and methanol (5 mL). Palladium catalyst (30 mg, 65% by wt) was added to the reaction. The mixture was exposed to hydrogen gas for 60 minutes at room temperature and atmospheric pressure. The mixture was passed through celite to remove palladium catalyst. Removal of organic solvents in vacuo and purification by flash chromatography provided 4-(azetidin-3-yloxy)-1-(4-methanesulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidine as a white solid (11 mg, 5%). 1H NMR (400 MHz, MeOH-d4) δ (ppm): 8.45 (m, 2H); 8.37 (d, 2H); 8.05 (d, 2H); 4.54 (m, 1H); 4.35 (dd, 2H); 3.69 (m, 2H); 3.09 (s, 3H). LCMS (ESI), m/z 346.2 (M+H+, 100%).
