51762-67-5, name is 3-Nitrophthalonitrile, belongs to nitriles-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 3-Nitrophthalonitrile
3-nitrophthalicnitrile (20 mmol) and dipotassium 2-naphthol-6,8-disulfonate (20-70 mmol, preferably 60 mmol) as reactants, dimethyl sulfoxide (40-200 mL) , preferably 140 mL) is a solvent, and the reaction is stirred at room temperature ~ 60C (preferably 60C) for 24 to 72 hours in the presence of potassium carbonate (30 to 90 mmol, preferably 80 mmol) and nitrogen, monitored by thin layer chromatography. The insoluble potassium carbonate was removed from the reaction mixture by filtration, and the filtrate was added with 30 mL of ice-cold chloroform to precipitate a yellow-white precipitate that was filtered, washed with ethanol and acetone until the solution was colorless.Vacuum dried at 50CdryGet 3-(6,8-disulfo-2-naphthyloxy)phthalimide dipotassium saltThe yield is 93%.
The synthetic route of 51762-67-5 has been constantly updated, and we look forward to future research findings.
