To a sealed tube was added 1-[2-amino-6-(methylamino)pyrimidin-4-yl]-6-iodo-N,N-dimethyl-1H-indazole-3-carboxamide (86 mg, 0.20 mmol), followed by piperidine (2 mL), tetrakis(triphenylphosphine)palladium (23 mg, 0.02 mmol), copper(I) iodide (4 mg, 0.02 mmol) and 2-(pyrimidin-2-yl)but-3-yn-2-ol (58 mg, 0.39 mmol). The reaction mixture was purged with nitrogen gas, capped and stirred at room temperature for 1.5 hr. After cooling to RT, the reaction mixture was concentrated in vacuo. EtOAc (5 mL) was added and concentration in vacuo repeated. The residue was purified using column chromatography (Biotage, 0-10% gradient of methanol in DCM) to give a brown solid. Trituration of the solid with ethyl acetate/heptane gave the title compound. 1H NMR (DMSO, 500 MHz) delta 1.92 (3H, s), 2.80 (3H, d, J=4.1 Hz), 3.10 (3H, s), 3.31 (3H, s), 6.26 (2H, s), 6.49 (2H, s), 7.11 (1H, s), 7.30 (1H, d, J=8.4 Hz), 7.51 (1H, t, J=4.9 Hz), 7.94 (1H, d, J=8.4 Hz), 8.78-9.04 (3H, m); LC-MS: m/z=+458.10 (M+H)+.
