反応手順

The title compound was prepared in a similar manner as described for example 12 from 6-bromo-1-(1-methylethyl)-N-[(6-methyl-2-oxo-4-methyl-1,2-dihydro-3-pyridinyl)methyl]-1H-indazole-4-carboxamide (100 mg, 0.240 mmol) and dimethyl{[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]methyl}amine (93 mg, 0.312 mmol). The product obtained from HPLC purification was treated with a saturated solution of NaHCO3, solids that crashed out were filtered, and air-dried for 15 min. The product was then triturated first from EtOAc (containing EtOH) and then hexanes. The solid was then concentrated from MeOH, and triturated with ether, and then dried in vacuum oven overnight. The product was collected as a white solid (56 mg, 56%). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.53 (s, 1H) 8.66 (t, J=4.93 Hz, 1H) 8.37 (s, 1H) 8.09 (s, 1H) 7.83 (s, 1H) 7.71-7.76 (m, 2H) 7.46 (t, J=7.96 Hz, 1H) 7.33 (d, J=7.58 Hz, 1H) 5.89 (s, 1H) 5.19 (quin, J=6.63 Hz, 1H) 4.40 (s, 1H) 4.39 (s, 1H) 3.49 (s, 2H) 2.22 (s, 3H) 2.19 (s, 6H) 2.12 (s, 3H) 1.51 (s, 3H) 1.49 (s, 3H); LC-MS (ES) m/z=472.2 [M+H]+
