75% | With silver hexafluoroantimonate; dichloro(pentamethylcyclopentadienyl)rhodium (III) dimer; oxygen; silver carbonate; Trimethylacetic acid; In 1,2-dichloro-benzene; at 140℃; for 24h;Schlenk technique; Sealed tube; | General procedure: A 25 mL flame-dried Schlenk tube was charged with the1-(pyrimid-2-yl)-1H-indoles 1 (0.25 mmol), 1,3-azoles2 (0.75 mmol), [RhCp*Cl2]2 (3.9 mg, 2.5 mol%), AgSbF6(8.6 mg, 10 mol%), pivalic acid (PivOH,51 mg, 0.50 mmol), Ag2CO3 (6.9 mg, 10 mol%), and DCB(1.0 mL). The tube was sealed under an O2 atmosphere.The reaction mixture was stirred vigorously and heated at140 C for 24 h, and then cooled to ambient temperature.The final reaction mixture was diluted with 10-20 mL ofCH2Cl2, filtered through a Celite pad to remove insolublesalts, and then washed with 10-20 mL of CH2Cl2. Thecombined CH2Cl2 extracts were concentrated in a vacuumevaporator and the crude product was purified by flashcolumn chromatography on silica gel (petroleum ether/ethylacetate=3/1, v/v) to give the desired product 3 or 4. |
