64248-58-4, name is 1,2-Difluoro-4-iodobenzene, 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. Quality Control of 1,2-Difluoro-4-iodobenzene
A mixture of methyl indole-5-carboxylate 24a (2 g, 11.4 mmol), 1-iodo-3,4-difluoro-benzene 24b (1.5 mL, 12.5 mmol), CuI (0.22 g, 1.14 mmol), trans-N,N’-dimethylcyclohexane-1,2-diamine (0.54 mL, 3.43 mmol), and K3PO4 (6.06 g, 28.5 mmol) in toluene (12 mL) was heated at 110 C. for 7 hours. The reaction mixture was diluted with CH2Cl2 and filtered. The solution was concentrated and the residue was purified by flash column chromatography (silica gel, 20% EtOAc/heptane) to give 24c (3.0 g).
The synthetic route of 64248-58-4 has been constantly updated, and we look forward to future research findings.
