With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1204-75-7,3-Oxo-3,4-dihydroquinoxaline-2-carboxylic acid,as a common compound, the synthetic route is as follows.
To a stirred solution of Zn(ClO4)2¡¤6H2O (18.7 mg, 0.05 mmol) in H2O (2 mL) was added 1 equiv. of 4,4′-bpy (7.8 mg, 0.05 mmol) in CH3OH (5 mL). This was stirred for 5 min, and then a 5 mL CH3OH solution of Hqc (9.5 mg, 0.05 mmol) was added to the reaction mixture and then filtered to give an orange solution. Slow evaporation of the solvent at room temperature gave rise to colorless block single crystals suitable for X-ray single-crystal analysis after 2 weeks (Yield 42%). Anal. Calc. for C28H18N6O6Zn: C, 56.06; H, 3.02; N, 14.01. Found: C, 55.93; H, 3.09; N, 14.12%. IR (KBr)/cm-1: 3066(w), 1654(s), 1503(m), 1449(s), 1349(m), 1283(w), 1227(w), 1010(w), 820(w), 553(m), 442(w).
1204-75-7, 1204-75-7 3-Oxo-3,4-dihydroquinoxaline-2-carboxylic acid 71001, aquinoxaline compound, is more and more widely used in various fields.
