Electric Literature of 96606-37-0, These common heterocyclic compound, 96606-37-0, name is 2,4,6-Trifluorobenzonitrile, 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.
In analogy to GP 2, 1 g of 2,4,6-trifluoro-benzonitrile (6.37 mmol; 1 eq.; commercially available) and 2.26 g 2-fluoro-4-iodo-benzenamine (9.55 mmol, 1.5 eq; commercially available) were dissolved in 100 ml of THF. The mixture was cooled to -65 C; 2.14 g of potassium tert-butoxide (19.1 mmol, 3 eq; commercially available) were added. The mixture was stirred for 35 min at this temperature and another 21 h at RT. The mixture was stirred into 120 ml of ice water and extracted three times with ethyl acetate (100 ml each). The combined organic layers were washed with brine, dryed over sodium sulfate and concentrated to afford 4.137 g of crude product. Purification was achieved by flash chromatography (hexane/ethyl acetate) to afford 646 mg (27.13% yield; 1.73 mmol) of the target compound.
The synthetic route of 96606-37-0 has been constantly updated, and we look forward to future research findings.
