Related Products of 156150-67-3,Some common heterocyclic compound, 156150-67-3, name is 2-Chloro-1-fluoro-4-iodobenzene, molecular formula is C6H3ClFI, 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.
INTERMEDIATE 4; 2-(2-ChloiO-4-iodophenylamino)-5,5-dimethyl-8-oxo-5,6.7.8-tetrahydro-4H-thieno[“2,3- c”|azepine-3-carboxylic acid ethyl ester Caesium carbonate (2.77 g, 8.51 mmol) and 2-chloro-4-iodo-l-fluorobenzene(2.18 g, 8.51 mmol) were added to a solution of 2-amino-5,5-dimethyl-8-oxo-5, 6,7,8- tetrahydro-4i7-thieno[2,3-c]azepine-3-carboxylic acid ethyl ester (WO 2007/141504, Intermediate 20) (2.0 g, 7.09 mmol) in DMF (20 mL) and heated at 650C for 18 h. Brine (100 mL) was added to the reaction and the mixture extracted with DCM (3 x 50 mL). The combined organic extracts were dried (MgSO4) and concentrated in vacuo. The residual DMF was azeotroped with heptane. The crude product was purified by chromatography (silica, 0-30% EtOAc in DCM) to give the title compound as a cream solid (916 mg, 25%). deltaH (DMSO-d6) 10.60 (IH, s), 8.01 (IH, t, J 5.0 Hz), 7.95 (IH, d, J
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Chloro-1-fluoro-4-iodobenzene, its application will become more common.
