Reference of 40400-15-5,Some common heterocyclic compound, 40400-15-5, name is 2-(2-Iodophenyl)acetonitrile, molecular formula is C8H6IN, 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 flask was equipped with a magnetic stir bar and charged with 1Hpyrrole-2-carbaldehyde (2a; 19.0 mg, 0.2 mmol, 1.0 equiv), 2-bromophenylacetonitrile(1a; 39.2 mg, 0.2 mmol, 1.0 equiv), and K3PO4(63.6 mg, 0.3 mmol, 1.5 equiv). The flask was evacuated and filledwith N2, and then anhydrous DMSO (2.0 mL) was introduced via a syringe.The flask was heated in a 130 C oil bath for 24 h, at which timeTLC analysis [petroleum ether (bp 60-90 C)-EtOAc, 10:1] indicatedcomplete consumption of 2a and 1a. The reaction mixture was cooledto r.t. and added to a sat. solution of NaCl (20 mL) and extracted withEtOAc (3 ¡Á 10 mL). The combined organic layers were dried (Na2SO4)and filtered. The filtrate was concentrated, and the residue was purified by column chromatography on SiO2 [petroleum ether (bp 60-90C)-EtOAc, 10:1 to 30:1] to give 3ag; Yield: 50.8 mg (99%); fluorescent yellow solid; mp 199.4-201.1 C.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(2-Iodophenyl)acetonitrile, its application will become more common.
