Procedure
To a sealed tube was added 1-(2-aminopyrimidin-4-yl)-6-bromo-N,N-dimethylindazole-3-carboxamide (55%, 113 mg, 0.172 mmol), followed by piperidine (2 mL), tetrakis(triphenylphosphine)palladium (40 mg, 0.034 mmol), copper(I) iodide (7 mg, 0.034 mmol) and 2-(1,3-thiazol-2-yl)but-3-yn-2-ol (105 mg, 0.688 mmol). The reaction mixture was purged with nitrogen gas, capped and stirred at 60° C. for 1.5 hr. Reaction mixture was concentrated in vacuo. EtOAc (5 mL) added. Concentration in vacuo was repeated. The residue was purified using column chromatography (Biotage, 100% DCM to 10% MeOH/DCM) to give a brown solid. Trituration of the solid with DCM gave the title compound: 1H NMR (500 MHz, DMSO) delta 1.95 (3H, s), 3.12 (3H, s), 3.33 (3H, s), 7.12 (2H, s), 7.13-7.19 (2H, m), 7.42 (1H, dd, J=8.35, 1.42 Hz), 7.71 (1H, d, J=3.31 Hz), 7.80 (1H, d, J=3.15 Hz), 7.97-8.07 (1H, m), 8.35 (1 H, d, J=5.52 Hz), 8.94 (1H, s); LC-MS: m/z=+434.45 (M+H)+.
