6828-35-9, name is 5-Chloro-2-iodoaniline, belongs to iodides-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. Formula: C6H5ClIN
General procedure: 2-aminobenzenethiol (10 g, 80mmol), 3, 4-difluorobenzonitrile (11.12, 80mmol) and ferric citrate (19.59g, 80mmol) were added in DMF (50.00 mL) at 25-30 0C. The reaction mixture was heated to 110C. Reaction mixture was monitored for the synthesis of compound 3 by TLC. (2ml of reaction mixture was withdrawn and separated in ethylacetate and water. Ethyl acetate solution concentrated and crystallised in isopropyl ether to give compound 3 for characterization). After completion of reaction by TLC, powdered potassium carbonate (16.58 g, 120mmol) was added to the solution and stirred for 1 hr. The mixture was heated to 110C till completion by TLC. After completion of reaction, the mass was cooled to 25-30 C. Ethyl acetate (150 mL) and DM water (150 mL) were added. Layers separated. Organic layer washed with water (150 mL), dried over sodium sulfate and concentrated. Isopropyl ether (IPE; 150 mL) was added to the slurry, filtered, washed with IPE. Dried under vacuum at 50 C (16.84g, 94%).
The synthetic route of 6828-35-9 has been constantly updated, and we look forward to future research findings.
