실험 절차

3-(4-Phenoxyphenyl)-1-tetrahydro-1H-3-pyrrolyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (150 mg, 0.403 mmol), 1-methyl-4-piperidone (0.099 mL, 0.806 mmol), sodium triacetoxyborohydride (113 mg, 0.537 mmol) and glacial acetic acid (48 mg, 0.806 mmol) were mixed with 1,2-dichloroethane (4 mL). The reaction mixture was stirred at room temperature for 6 hours and saturated sodium bicarbonate solution was added to adjust the pH to about 9. The aqueous layer was extracted with dichloromethane. The combined organic layer was washed with brine, dried over MgSO4, filtered and evaporated. The residue was purified by flash column chromatography using dichloromethane/methanol (85:15) as mobile phase to give 1-[1-(1-methyl-4-piperidyl)tetrahydro-1H-3-pyrrolyl]-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (148 mg, 78%). 1H NMR (DMSO-d6) δ 1.42 (m, 2H), 1.81 (m, 2H), 1.92 (m, 2H), 2.15 (m, 1H), 2.26 (m, 2, 3H), 2.28 (m, 2H), 2.75 (m, 4H), 2.86 (m, 1H), 3.22 (m, 1H), 5.36 (m, 1H), 7.16 (m, 5H), 7.44 (m, 2H), 7.67 (m, 2H), 8.24 (s, 1H).
