実験手順

The mixture of 6-fluoro-3-(tributylstannyl)-1H-indazole (500 mg, 1.17 mmol), 2-bromo-N-tert-butyl-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (258 mg, 0.9 mmol), tetrakis(triphenylphosphine)palladium(0) (20 mg, 0.017 mmol), copper iodide (10 mg 0.052 mmol) in 15 ml, of dry DMF was heated to 90° C. for 2.5 hours under nitrogen atmosphere. The reaction mixture was cooled to room temperature, diluted with 50 mL of water and filtered. The solid was washed with dichloromethane and hot methanol, then filtered to give N-tert-butyl-2-(6-fluoro-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide as a yellow solid (260 mg, 82%). 1H NMR (300 MHz, DMSO): δ 13.82 (s, 1H), 12.96 (s, 1H), 9.10 (s, 1H), 8.48-8.43 (m, 1H), 8.33 (s, 1H), 7.92 (s, 1H), 7.44-7.41 (m, 1H), 7.12-7.06 (m, 1H), 3.14 (d, 1H, J=5.1 Hz), 1.51 (s, 9H). LCMS: 353.0, [M+H]+.
