6-(Dimethylamino)pyridine-3-boronic acid → 6-[6-(dimethylamino)-3-pyridinyl]-3-methyl-1-(1-methylethyl)-N-[(6-methyl-2-oxo-4-propyl-1,2-dihydro-3-pyridinyl)methyl]-1H-indazole-4-carboxamide

Reaction Steps

The title compound was prepared in the same manner as described for example 67 from 6-bromo-3-methyl-1-(1-methylethyl)-N-[(6-methyl-2-oxo-4-propyl-1,2-dihydro-3-pyridinyl)methyl]-1H-indazole-4-carboxamide (0.079 g, 0.172 mmol) and [6-(dimethylamino)-3-pyridinyl]boronic acid (0.034 g, 0.206 mmol). The product was triturated from EtOAc spiked with DCM, and dried in a hi-vacuum oven for 4 h. The title compound was collected as a white solid (49 mg, 56%); 1H NMR (400 MHz, DMSO-d6) δ ppm 0.93 (t, J=7.33 Hz, 3H), 1.45 (d, J=6.57 Hz, 6H), 1.51-1.64 (m, 2H), 2.12 (s, 3H), 2.42 (s, 3H), 2.52-2.59 (m, 2H), 3.08 (s, 6H), 4.38 (d, J=5.05 Hz, 2H), 4.96-5.09 (m, 1H), 5.90 (s, 1H), 6.75 (d, J=9.09 Hz, 1H), 7.31 (d, J=1.26 Hz, 1H), 7.86 (d, J=1.26 Hz, 1H), 7.96 (dd, J=8.97, 2.65 Hz, 1H), 8.40 (t, J=4.93 Hz, 1H), 8.55 (d, J=2.27 Hz, 1H), 11.50 (s, 1H); LCMS (ES+) m/z: 501.1.
