1953-99-7, name is 3,4,5,6-Tetrachlorobenzene-1,2-dicarbonitrile, 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. Application In Synthesis of 3,4,5,6-Tetrachlorobenzene-1,2-dicarbonitrile
Synthesis Example 3: Synthesis of 3,4,6-trichloro-5-(2,6-dibromo-phenoxy)-phthalonitrile 5 g of 3,4,5,6-tetrachlorophthalonitrile, 4.75 g of 2,6-dibromophenol, 3.9 g of K2CO3, and 25 ml of N,N-dimethyl formamide were put in a 100 ml flask and stirred while heated at 70° C. When the reaction was complete, EA (ethyl acetate) was used for an extraction. After the extraction, the resultant was concentrated to obtain a solid. The obtained solid was dissolved in a small amount of dichloromethane, several times washed with hexane, filtered, and vacuum-dried to obtain 3,4,6-trichloro-5-(2,6-dibromo-phenoxy)-phthalonitrile.
The synthetic route of 1953-99-7 has been constantly updated, and we look forward to future research findings.
