82031-32-1, 7-Bromoquinoxalin-2(1H)-one is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
82031-32-1, 6.00 mg (2.67 mmol) of 7-bromoquinoxalin-2(lH)-one [Lumma et al., J. Med. Chem. 1981, 24, 93] and 1.73 ml (3.47 mmol) trimethylsilyldiazomethane were taken up in 5.25 ml methanol/acetonitrile/dichloromethane (1/10/10). Then 0.483 ml (3.47 mmol) triethylamine was added and it was stirred overnight at room temperature. The mixture was concentrated by evaporation and the residue was purified by MPLC (Puriflash Analogix: 4OM: isohexane / ethyl acetate = 9 / 1 ? isohexane / ethyl acetate = 3 / 1). We obtained 140 mg (22% of theor.) of the target compound.LC-MS (method 10): R, = 1.09 min; MS (EIpos): m/z = 240 [M+H]+.IH-NMR (400 MHz, DMSO-D6): delta [ppm] = 4.04 (s, 3H), 7.78 (dd, IH), 7.96 (d, IH), 8.06 (d, IH), 8.64 (s, IH).
82031-32-1 7-Bromoquinoxalin-2(1H)-one 4913264, aquinoxaline compound, is more and more widely used in various fields.
