Reaktionsschritte

A solution of 3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.452 g, 0.00149 mol) in N,N-dimethylformamide (10 mL) was reacted with cis 3-[(benzyloxy)methyl]cyclobutyl methanesulfonate (0.483 g, 0.00179 mol) and cesium carbonate (0.582 g, 0.00179 mol) at 70° C. for two days. The reaction mixture was poured into water (30 mL) and extracted with ethyl acetate (3×15 mL). The combined organic layers were washed with water (2×20 mL) and brine (20 mL). The organic layer was 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 trans 1-{3-[(benzyloxy)methyl]cyclobutyl}-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.325 g, 0.000681 mol) as a tan solid.
