Sodium borohydride → HCID 178508617, compound

Participants

Reaction Steps

A solution of 3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-cyclobutanone (0.208 g, 0.00056 mol) in tetrahydrofuran (10 mL) and absolute ethanol (5 mL) was reacted with sodium borohydride (0.021 g, 0.00056 mol) at room temperature for four hours. Added water (5 mL) and extracted with ethyl acetate (3×15 mL). The combined organics were dried over magnesium sulfate, and the solvent was removed in vacuo. The residue was purified by flash column chromatography on silica using dichloromethane/methanol (98:2). The solvent was removed in vacuo to give cis 3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-cyclobutanol (0.090 g, 0.00024 mol) as a white solid.
