反応手順

trans-2-phenyl-1-cyclopropanecarbonyl chloride (32 mg, 0.176 mmol) in dichloromethane (0.3 mL) was added to a solution of trans-3-(4-amino-2-fluoro-5-methoxyphenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (80 mg, 0.176 mmol) in pyridine (1.5 mL) at 0° C. After 5 minutes the ice-water bath was removed and the reaction mixture was stirred at room temperature for 3 hours. More trans-2-phenyl-1-cyclopropanecarbonyl chloride (32 mg, 0.176 mmol) was added to ensure the reaction went to completion. Solvent was evaporated and the residue was purified by flash column chromatography to give trans-N1-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-5-fluoro-2-methoxyphenyl)-2-phenyl-1-cyclopropanecarboxamide (93 mg, 88%). 1H NMR (DMSO-d6) δ 1.35 (m, 1H), 1.50 (m, 3H), 1.98 (m, 6H), 2.19 (s, 3H), 2.37-2.68 (m, 11H), 3.87 (s, 3H), 4.64 (m, 1H), 7.09 (m, 1H), 7.21 (m, 3H), 7.31 (m, 2H), 8.21 (m, 2H), 9.82 (m, 1H).
