Versuchsvorschrift

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-methyl-1,2-dihydro-3-pyridinyl)methyl]-1H-indazole-4-carboxamide (90 mg, 0.216 mmol) and 1-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-pyridinyl]piperazine (94 mg, 0.324 mmol). The product obtained from HPLC purification was treated with a saturated solution of NaHCO3, and solids that crashed out were filtered. The product was evaporated from MeOH, triturated from ether and then CH3CN. After drying in vacuum oven overnight, the final product was collected as a white solid (87 mg, 78%). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.53 (br. s., 1H) 8.59-8.67 (m, 2H) 8.54 (s, 1H) 8.35 (s, 1H) 8.02-8.09 (m, 2H) 7.84 (s, 1H) 6.94 (d, J=9.09 Hz, 1H) 5.89 (s, 1H) 5.14 (dt, J=13.07, 6.47 Hz, 1H) 4.39 (br. s., 1H) 4.38 (br. s., 1H) 3.41-3.47 (m, 4H) 3.17 (s, 1H) 2.22 (s, 3H) 2.13 (s, 3H) 1.50 (s, 3H) 1.49 (s, 3H). LC-MS (ES) m/z=500.4 [M+H]+ Note: some piperinzyl proton atoms hidden under water peak.
