Simple exploration of 89898-96-4

As the paragraph descriping shows that 89898-96-4 is playing an increasingly important role.

89898-96-4, 7-Nitro-2(1H)-quinoxalinone is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a solution of compound V (17.570 g, 91.50 mmol, 1 equiv.) in 80 mE of P0C13 are added 30 drops of dimethylformamide. The reaction mixture is then refluxed for 3 h. The colour of the reaction mixture turns black. After cooling, the reaction mixture is poured slowly into a 500-mE beaker filled with crushed ice. The precipitate is collected by filtration and washed with water. The solid obtained is dried under vacuum for 48 h to give compound VI in the form of a grey solid (17.02 g, 88%). ?H NMR (300 MHz, CDC13) oe ppm: 8.30 (d, J=9.3 Hz, 1H), 8.56 (dd, J=9.3 and 2.2 Hz, 1H), 8.92 (d, J=2.5 Hz, 1H), 8.93 (s, 1H). ?3C NMR (75 MHz, CDC13) oe ppm: 123.7, 124.8, 131.1, 141.1, 143.2, 148.0, 148.7, 149.8.
