156150-67-3, name is 2-Chloro-1-fluoro-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 2-Chloro-1-fluoro-4-iodobenzene
A mixture of 2-chloro-1-fluoro-4-iodobenzene (7.0 g, 27.3 mmol), 4, 4, 5, 5-tetramethyl-2- (1, 4-dioxaspiro [4.5] dec-7-en-8-yl) -1, 3, 2-dioxaborolane (7.2 g, 27.1 mmol), Pd (dppf) Cl2 (1.0 g, 1.36 mmol) and Cs2CO3 (14.0 g, 42.9 mmol) in 1, 4-dioxane (200 mL) was heated at 95 for 2 hours. The mixture was filtered and the filtrate was concentrated and the resulted residue was purified by column chromatography (PE: EA=50: 1 to 20: 1) to give product (3.8 g, crude) as a colorless oil.
The synthetic route of 156150-67-3 has been constantly updated, and we look forward to future research findings.
