Electric Literature of 40400-15-5, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 40400-15-5 as follows.
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 × 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 3af; Yield: 59.2 mg (93%); fluorescent yellow solid; mp 205.6-207.1 C.
According to the analysis of related databases, 40400-15-5, the application of this compound in the production field has become more and more popular.
