実験手順
A mixture of azaindole 3 (80 mg, 0.23 mmol), 2-chloropyridine-4-boronic acid (41 mg, 0.27 mmol), Pd(Ph3P)4 (20 mg, 0.11 mmol) and 2 M sodium carbonate (0.34 mL, 0.68 mmol) in 2 mL of DME was microwaved on high at 160° C. for under nitrogen for 15 minutes. Diluted with ethyl acetate and the organic phase washed with water and brine then dried (Na2SO4) and concentrated in vacuo. The residue was subjected to flash chromatography (40% EtOAc/60% hexanes) to give 60 mg (68%) of the desired product 14. 1H NMR CDCl3 8.6 (d, 2H), 8.1 (m, 4H), 7.25 (m, 5H), 2.5 (s, 3H). The 2-chloropyridine could be displaced, for example, with benzylamine in a microwave reaction at 250° C. for 30 min followed by deprotection to give compound 15.
