Some common heterocyclic compound, 67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile, molecular formula is C8H3F4N, 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. Product Details of 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 THE at-10 C 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/EtOAc 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).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 67515-59-7, its application will become more common.
