Reference of 216393-67-8, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 216393-67-8, name is 4-Chloro-2-fluoro-6-iodoaniline, This compound has unique chemical properties. The synthetic route is as follows.
4-Chloro-2-fluoro-6-iodoaniline (0.100 g; 0.368 mmol), 4-(3-fluorobenzyl)-N-(4-(triethylsilyl)but-3-ynyl)benzamide (0.145 g; 0.368 mmol), bis(diphenylphosphino)ferrocene]palladium(II) chloride (0.015 g; 0.018 mmol), lithium chloride (0.016 mg; 0.368 mmol) and sodium carbonate (0.078 g; 0.737 mmol) were suspended in DMF (5 mL) and the mixture was stirred at 100 C. for 18 hours. The solution was concentrated under reduced pressure and diluted in ethyl acetate. The organic layer was successively washed with brine, sodium thiosulfate, dried and concentrated under reduced pressure. The crude residue was purified by flash chromatography on silica gel (eluent 2 to 60% ethyl acetate in heptane) to afford 0.102 g (51%) of the title compound as a yellow oil. [0672] ESI/APCI(+): 539 (M+H).
The chemical industry reduces the impact on the environment during synthesis 4-Chloro-2-fluoro-6-iodoaniline. I believe this compound will play a more active role in future production and life.
