Electric Literature of 61881-19-4, These common heterocyclic compound, 61881-19-4, name is 2,2,2-Trifluoro-N-phenylacetimidoyl chloride, its 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: In a typical experimental procedure, a dry, two-necked, 50 mL round-bottomed flask equipped with a nitrogen inlet was charged with 5 mL of dry MeCN, 0.117 g (1.0 mmol) of indole and 0.24 g (1.0 mmol) of NaH. The solution was stirred under a nitrogen atmosphere at room temperature for 30 min, then a solution of 2a (1.0 mmol in 2 mL of dry MeCN) was added dropwise via a syringe. The mixture was stirred at room temperature for 20 h under an N2 atmosphere and then filtered. After removing the solvent under reduced pressure, the crude product was purified by preparative thin-layer chromatography on silica gel [eluent: n-hexane/EtOAC, 4:1] to give the product 4a. The products obtained from indole-3-carbaldehyde were purified by recrystallization from EtOH (twice).
Statistics shows that 2,2,2-Trifluoro-N-phenylacetimidoyl chloride is playing an increasingly important role. we look forward to future research findings about 61881-19-4.
