実験手順

A mixture of 2-chloro-4-iodo-furo[2,3-c]pyridin-7-ylamine (2 g, 7 mmol), [1-(trans-4-{[tert-butyl(dimethyl)silyl]oxy}cyclohexyl)-1H-pyrazol-4-yl]boronic acid (2.75 g, 8.49 mmol), (1,1′bis-(diphenylphosphino)-ferrocene)palladium dichloride (248 mg, 0.340 mmol) and potassium carbonate (2.35 g, 17.0 mmol) in 1,4-dioxane (20 mL) and water (9.5 mL) was heated to 70° C. for 22 h. The mixture was partitioned between ethyl acetate and water and the aqueous phase extracted with DCM. The combined organic extracts were dried over sodium sulfate, filtered, and concentrated. Purification by ISCO chromatography (10% to 50% ethyl acetate:heptane) followed by trituration with ether:heptane afforded 2.0 g (60%) of the title compound as an off-white solid. 1H NMR (400 MHz, CDCl3): δ 7.97 (s, 1 H), 7.76-7.69 (m, 1 H), 7.62 (s, 1 H), 6.73 (s, 1 H), 4.73 (s, 2 H), 4.17 (tt, J=3.9, 11.6 Hz, 1 H), 3.73 (tt, J=4.3, 10.5 Hz, 1 H), 2.23 (d, J=12.1 Hz, 2 H), 2.09-1.99 (m, 2 H), 1.91 (dq, J=3.5, 11.9 Hz, 2 H), 1.61-1.48 (m, 2 H), 0.92 (s, 9 H), 0.10 (s, 6 H); MS (ESI): 447.39, 449.35 [M+H]+.
