Some common heterocyclic compound, 453565-55-4, name is 5-Fluoroisophthalonitrile, molecular formula is C8H3FN2, 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. 453565-55-4

Example 15 To a solution of 1-(3-hydroxyphenyl)ethanol (69 mg) in 1-methyl-2-pyrrolidinone under a nitrogen atmosphere was added sodium hydride (60% in oil, 44 mg). The mixture was stirred at 20 C. for 10 minutes then 5-fluoroisophthalonitrile (0.161 g) was added and the mixture heated at 100 C. for 0.5 hour then at 150 C. for a further 0.5 hour. The cooled mixture was diluted (ethyl acetate), washed (water), dried over magnesium sulphate, evaporated and purified by dry column chromatography on silica (eluent dichloromethane/isohexane) to yield 1-(3,5-dicyanophenoxy)-3-[1-(3,5-dicyanophenoxy)ethyl]benzene (Compound 89, 84 mg), NMR (300 MHz, CDCl3) 7.56 (1H, t); 7.45-7.38 (2H, m); 7.32 (2H, d); 7.24 (2H, d); 7.22-7.18 (1H, m); 6.98 (1H, t); 6.92 (1H, dd); 5.29 (1H, quartet); 1.66 (3H, d).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 453565-55-4, its application will become more common.
