Reaction Steps

To a pressure tube was added 6-(6-iodoindazol-1-yl)-N-(2-methoxypyridin-3-yl)pyrimidin-4-amine (120 mg, 0.27 mmol) followed by triethylamine (2 mL) and THF (2 mL). Next, copper(I) iodide (5.15 mg, 0.027 mmol), bis(triphenylphosphine)palladium(II) chloride (18.96 mg, 0.027 mmol) and 2-methylbut-3-yn-2-ol (0.05 ml, 0.54 mmol) were added and the reaction vessel was sealed and stirred at RT for 1 h. The reaction mixture was concentrated in vacuo and DCM (5 ml) was added. The organics were washed with 0.5M HCl (2×3 ml), water (3 ml) and brine (3 ml), and dried (Na2SO4), filtered and concentrated in vacuo. The crude product was purified by flash chromatography (Isolute column, 4:6 to 1:1 EtOAc:heptanes) to surrender the title compound as a white solid: 1H NMR (500 MHz, CDCl3) delta 1.69 (6H, s), 2.08 (1H, br. s.), 4.07 (3H, s), 6.99 (1H, dd, J=7.80, 4.97 Hz), 7.32-7.41 (2H, m), 7.69 (1H, d, J=8.20 Hz), 7.88 (1H, dd, J=4.97, 1.66 Hz), 8.19 (1H, s), 8.54-8.61 (1H, m), 8.77 (1H, s), 8.99 (1H, s); LC-MS: m/z=+401.10 (M+H)+.
