실험 절차

A stirred slurry of methyl 4-chloro-7-azaindole-2-carboxylate (100 mg, 0.48 mmol), tert-butyl 3-(hydroxy(methyl)boryl)benzoate (137 mg, 0.62 mmol), potassium phosphate (309 mg, 1.42 mmol), tetrakis(triphenylphosphine) palladium (28 mg, 0.02 mmol) in p-dioxane (3 mL)/water (1 mL) were heated at 100° C. for 15 hr. The reaction mixture was cooled, concentrated in vacuo and flash chromatographed (0-100% ethyl acetate:heptanes) to afford methyl 4-(3-(tert-butoxycarbonyl)phenyl)-1H-pyrrolo[2,3-b]pyridine-2-carboxylate as a white powder (148 mg). 1H NMR (400 MHz, CHLOROFORM-d) d ppm 1.62 (s, 9H) 3.99 (s, 3H) 7.28 (d, J=5.23 Hz, 1H) 7.36 (d, J=2.62 Hz, 1H) 7.59 (t, 1H) 7.90 (d, 1H) 8.09 (d, 1H) 8.35 (t, 1H) 8.64 (d, J=4.70 Hz, 1H); m/z (M+1)=353.2.
