Related Products of 123158-75-8,Some common heterocyclic compound, 123158-75-8, name is 4-Chloro-2-iodo-6-nitroaniline, molecular formula is C6H4ClIN2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(Step 1)2-Iodo-4-chloro-6-nitro-phenylamine (10.0 g, 33.50 mmol) of was dissolved in 200 ml of tetrahydrofuran, and 3.97 g (50.25 mmol) of pyridine and 7.74 g (36.85 mmol) of trifluoroacetic anhydride were added. The mixture was stirred for 9 hours at 0 C.room temperature. At the end of reaction, the reaction mixture was diluted with water and extracted with ethylacetate. The extract was washed with saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and separated by column chromatography to obtain trifluoroacetamide 12.3 g (Yield 85%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Chloro-2-iodo-6-nitroaniline, its application will become more common.
