Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 19472-74-3, name is 2-Bromophenylacetonitrile, A new synthetic method of this compound is introduced below., HPLC of Formula: C8H6BrN
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.
The synthetic route of 19472-74-3 has been constantly updated, and we look forward to future research findings.
