実験手順

A mixture of trifluoroacetic acid/dichloromethane (20:80, 200 mL) was added to a solution of N-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)carbamate(10.85 g, 20.24 mmol) in dichloromethane (100 mL) at 0° C. 2 hours later, the ice-bath was removed and the solvents were evaporated and the residue was dissolved in dichloromethane. Sodium hydroxide (1.0N) was added to adjust the pH to about 10. The solid formed upon removal of organic solvent was collect by filtration to give cis-3-(4-amino-3-methoxyphenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (8.84 g, 100%). 1H NMR (CDCl3) δ 1.65 (m, 2H), 1.83 (m, 2H), 2.18 (m, 2H), 2.31 (s, 3H), 2.35-2.60 (m, 11H), 3.90 (s, 3H), 4.00 (bs, 2H), 4.89 (m, 1H), 5.61 (bs, 2H), 6.83 (d, J=7.78 Hz, 1H), 7.12 (m, 2H), 8.35 (s, 1H).
