실험 절차

To a mixture of 1-(3-azetanyl)-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.020 g, 0.000056 mol) and potassium carbonate (0.016 g, 0.00012 mol) in anhydrous N,N,-dimethylformamide (1 mL) was added acetic anhydride (0.009 g, 0.000084 mol) at room temperature. The reaction mixture was stirred for 1hours. The solvent was removed under reduced pressure. The residue was purified by RP-HPLC (Hypersilprep HS C18, 5 μm, 100×20 mm; 20%-85% over 7.5 min with 0.05 M ammonium acetate, 251 mL/min) to yield 1-{3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-azetany}-1-ethanone (0.014 g, 0.000035 mol).
