74.8% | With caesium carbonate; In N,N-dimethyl-formamide; at 100℃;Inert atmosphere; | Methyl 4-(5-(benzyloxy)-1H-indol-1-yl)-2-bromo-5-fluorobenzoate [0220] A mixture of 5-benzyloxy indole (11.2g, 0.05 mmol), methyl 2-bromo-4,5-difluoro-benzoate (12.6g, 0.05 mol) and Cs2C03 (24.4g, 0.075 mol) in DMF (150 mL) was stirred at 100 C under N2 atmosphere overnight. The mixture was cooled to room temperature and then filtrated. The filtrate was poured into 150 mL water. A gradual formation of a cream-colored precipitate was observed. Filtration gave the desired intermediate product as a cream-colored solid which is pure enough for further reaction (Yield: 17g, 74.8%). 1HNMR (500 MHz, DMSO-d6) delta: 8.02 (d, J=7 Hz, IH), 7.98 (d, J=l lHz, IH), 7.60 (s, IH), 7.48 (d, J=7.5 Hz, 2H), 7.39 (t, J=7.5 Hz, 2H), 7.32 (t, J=7 Hz, IH), 7.26 (d, J=8.5 Hz, 2H), 6.96 (d, J=8.5 Hz, IH), 6.68 (s, IH), 5.14 (s, 2H) and 3.91 (s, 3H) ppm. |

86% | With oxygen; copper(II) bis(trifluoromethanesulfonate); cobalt(II) chloride; In ethanol; at 40℃; under 760.051 Torr; for 48h;Sealed tube; | Add 2-methyl carboxylate to phenol (0.2mmol, 1.0equiv.), 5-benzyloxyindole (0.2mmol, 1.0equiv.), CoCl2 (1.3mg, 5mol%) in a 25ml sample bottle, Cu(OTf)2 (7.3mg, 10mol%) and magnet, sealed with a rubber stopper, vacuumed and then filled with O2, transfer 4ml of 95% ethanol with a syringe to a sealed sample bottle, and then the atmosphere in the bottle Communicate with 1atm O2. After the reaction is stirred at 40 for 48h, the solvent is removed by blowing air at a constant temperature of 30 for 1 hour. The residue is purified by column chromatography on silica gel. The eluent is petroleum ether/ethyl acetate 20:1 To 5:1 gradient elution. The target product was collected and the isolated yield was 86%. |
