Procedure
The title compound was prepared in a similar manner as described for example 8 from 6-bromo-1-(1-methylethyl)-N-[(6-methyl-2-oxo-4-propyl-1,2-dihydro-3-pyridinyl)methyl]-1H-indazole-4-carboxamide (100 mg, 0.225 mmol) and (6-methyl-3-pyridinyl)boronic acid (46 mg, 0.337 mmol). The product was collected as a white solid (99 mg, 94%). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.47 (br. s., 1H) 8.96 (d, J=2.02 Hz, 1H) 8.67 (br. s., 1H) 8.40 (s, 1H) 8.20 (s, 1H) 8.17 (dd, J=8.08, 2.53 Hz, 1H) 7.89 (s, 1H) 7.39 (d, J=8.08 Hz, 1H) 5.91 (s, 1H) 5.18 (quin, J=6.57 Hz, 1H) 4.43 (br. s., 1H) 4.42 (br. s., 1H) 2.52-2.58 (m, 5H) 2.13 (s, 3H) 1.52-1.58 (m, 2H) 1.52 (s, 3H) 1.50 (s, 3H) 0.88 (t, J=7.33 Hz, 3H).
