Versuchsvorschrift
Following the procedures as described in Example 136, 1H-pyrazol-4-ylboronic acid and 5-bromo-3-phenyl-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine were reacted and the product was deprotected to give 137 as a yellow solid (26 mg, 23%) over two steps. 1H NMR (400 MHz, DMSO) δ 12.9 (s, 1H), 9.05 (s, 1H), 8.37-8.09 (m, 5H), 7.56 (m, 1H), 7.44 (m, 1H)
