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.
