In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. 67515-59-7
A solution of 1.1 g (5.9 mmol) of 4-fluoro-3-trifluoromethylbenzonitrile and 485 mg (6.5 mmol) of (S)- (+)-2-BUTANOL in 10 mL of THF AT-10C was treated with 235 mg (5.9 mmol) of sodium hydride. The resulting mixture was stirred cold for 2 h, then quenched with 10 mL of H2O. The quenched solution was extracted with 30 mL of Et20, dried over MGS04 and concentrated. Chromatography on a Biotage 40M cartridge using 4: 1 v/v hexanes/Ethyl acetate as the eluant afforded 550 mg of the title compound : 1H NMR (500 MHz) 5 0.99 (t, J= 7.6, 3H), 1.35 (d, J= 6.2, 3H), 1.58-1. 83 (m, 2H), 4. 51 (septet, 1H), 7.04 (d, J= 8.7, 1H), 7.75 (d, J= 8.7, 1H), 7.85 (s, 1H).
The synthetic route of 67515-59-7 has been constantly updated, and we look forward to future research findings.
