실험 절차

To a solution of N-(3,4-difluorobenzyl)-2-isopropyl-6-hydroxy-1-(pyridin-2-ylmethyl)-1H-indole-3-carboxamide (Compound 220, 26 mg, 0.060 mmol) in dimethylformamide (1 ml) stirring at room temperature, was added cesium carbonate (83 mg, 0.25 mmol) and the reaction stirred for 5 minutes. 2-iodopyridine (0.05 mL, 0.09 g, 0.47 mmol) and then copper powder (7.0 mg, 0.11 mmol) was then directly added and the resulting mixture heated at 100° C. for 18 h. The reaction was cooled to room temperature, quenched with water, extracted with EtOAc, washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The residue was purified by flash column chromatography on silica gel (50% EtOAc-hexanes, 100 % EtOAc) to yield the title compound as a white solid.
