Adding a certain compound to certain chemical reactions, such as: 67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 67515-59-7, COA of Formula: C8H3F4N
A mixture of 4-fluoro-3-trifluoro-methylbenzonitrile (Fluorochem 2223; 10 g; 52.8 mmol; 1 eq.) and morpholine (Fluka 69880; 9.25 ml 105.7 mmol; 2 eq.) was stirred at 600C for 8 hours. The mixture was cooled and diluted with water. The precipitate was filtered and dried to afford the title compound (12.9 g, 95%) as a white solid. HPLC (Method B) : Rt 3.61 min (purity 99.1 %). LC/MS : 257.1 (M+H)+. 1H NMR (CDCI3, 400MHz) delta 7.92 (1 H, s), 7.78-7.81 (1 H, d), 7.32-7.35 (1 H, d), 3.84-3.87 (4H, m), 3.04-3.06 (4H, m).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Fluoro-3-(trifluoromethyl)benzonitrile, and friends who are interested can also refer to it.
