Reaktionsschritte

Prepared by a 2-step process from 4-(4-amino-2-fluorophenoxy)-1-(4-methoxybenzyl)-N-(1-methylpiperidin-4-yl)-1H-pyrazolo[3,4-b]pyridin-3-amine (prepared in Example 101, step A) and 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (prepared from methyl 2-oxo-2H-pyran-3-carboxylate with 4-fluoroaniline and followed by hydrolysis using the methods described in US Publication No. 2005/0239820) according to the procedure of Example 101. The crude was rinsed with Et2O to afford 14 mg (73%) of the desired product. LRMS (ESI pos) m/e 572.0 (M+1). 1H-NMR (400 MHz, CD3OD/CDCl3) δ 8.72 (d, 1H), 8.24 (d, 1H), 8.02 (dd, 1H), 8.02 (dd, 1H), 7.87 (d, 1H), 7.47 (m, 2H), 7.41 (m, 1H), 7.38 (m, 3H), 6.72 (m, 1H), 6.12 (d, 1H), 3.70 (m, 1H), 2.88 (d, 2H), 2.35 (s, 3H), 2.24 (m, 1H), 2.21 (m, 2H), 1.62 (m, 2H); 19F NMR (376 MHz, CD3OD/CDCl3) δ −112.6, −128.0.
