Copper(I) iodide (HPMC encapsulated) (one capsule) and 2,2’-bipyridyl (HPMC encapsulated) (one capsule) were added to a solution of indole (93.7 mg, 800 µmol), 2-bromopyridine (164 mg, 1.04 mmol, 1.3 eq.) and cesium carbonate (521 mg, 1.60 mmol, 2.0 eq.) in DMSO (2.5 mL) at room temperature and the reaction mixture was stirred at 150 °C for 5 hours. After cooling to room temperature, the solution was diluted with ethyl acetate (15 mL) and sat. Na2SO4 aq. (15 mL), and filtered through Celite pad. The filtrate was extracted with ethyl acetate (15 mL x 2) and the organic layer was dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography (ethyl acetate:hexane = 1:10 - 1:5) to afford N-(2-pyridyl)indole (71 mg, 46% yield) as a pale-yellow oil.
Experimenter’s Comments
The reaction mixture was monitored by UPLC. The material of the capsule is water-soluble HPMC (hydroxypropyl methylcellulose). The capsule has the shape shown in Fig. 1 and 2,2’-bipyridyl (ca. 500 μmol) and copper(I) iodide (ca. 800 μmol) are encapsulated in each capsule, respectively.
