Reference of 33348-34-4,Some common heterocyclic compound, 33348-34-4, name is 4-Amino-3-iodobenzonitrile, molecular formula is C7H5IN2, 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.
General procedure: A 25 mL Wattecs reaction tube was charged with 2-haloaniline 1 (0.6 mmol), potassium O-ethyl dithiocarbonate 2 (1.8 mmol),CuCl (0.06 mmol), and DMF (2 mL). The reaction vessel was flushed with argon three times and sealed. Then the mixture was stirred electromagnetically in an oil bath at 110C for 6 h.The reaction process was monitored by TLC on silica gel. After the reaction was completed, the reaction mixture was cooled to room temperature, and then HCl (3 mL, 3 mol/L) was added and stirred for another 30 min. The reaction mixture solution was extracted by ethyl acetate (3 ¡Á 20 mL). Subsequently, the combined organic solutions were dried by anhydrous sodium sulfate and the target product was purified by chromatography on a silica gel column (eluent: petroleum ether/ethyl acetate) togive the corresponding pure product 3. Complete characterization characterizationof the products (all known) is found in the Supplemental Materials (Figures S1-S13).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Amino-3-iodobenzonitrile, its application will become more common.
