実験手順

At 0° C., 3-[6-[4-(6-amino-pyridin-3-yl)-phenyl]-5-(4-chloro-phenyl)-4-oxo-4,5-dihydro-pyrazolo[3,4-d]pyrimidin-1-yl]-benzonitrile (prepared as described in example 28, 0.325 g, 0.629 mmol) is added to methanol saturated with hydrogen chloride gas (7 mL) with stirring. The reaction mixture is allowed to reach rt and stirred there for 24 h. The reaction mixture is then concentrated to a dry residue. It is taken in dry methanol (6 mL) and ammonium carbonate (0.593 g, 3.77 mmol) is added. After stirring at rt for 16 h, the reaction mixture is concentrated and the residue obtained is purified by preparative HPLC to afford 3-[6-[4-(6-ammo-pyridin-3-yl)-phenyl]-5-(4-chloro-phenyl)-4-oxo-4,5-dihydro-pyrazolo[3,4-d]pyrimidin-1-yl]-benzamidine. 1H NMR (Acetone-d6, 400 MHz) δ 11.32 (br, 2H), 8.88 (br, 2H), 8.72 (m, 2H), 8.40 (s, 1H), 8.25 (m, 2H), 7.95 (m, 2H), 7.83 (m, 1H), 7.65 (m, 5H), 7.45 (m, 4H), 7.14 (d, 1H); LC-MS calculated for C29H21ClN8O (M+H+) 533.2, found 533.1.
