2973-50-4, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 2973-50-4 as follows.
General procedure: N,N’-di(2-fluorophenyl)-4-methoxyl-isophthalamide(1a): Equipped a stirrer in a three-necked flask (100 ml), to a mixture of 2-fluoroaniline (1.11 g, 10.0 mmol),anhydrous tetrahydrofuran (15 ml) and dry pyridine (1 ml), dropwise added 4-methoxyl-isophthaloyl dichloride (1.17 g, 5.0 mmol) which had been dissolved in dry tetrahydrofuran (10 ml). After the mixture reaction at room temperature for 8 h under continuous stirring, the excess tetrahydrofuran was distilled off in vacuum. The residue was recrystallized by acetone. Its melting point is 204-206 C, and yield is 67%. The other compounds 1b-1j, 2a-2k, 3a-3l and 4a-4h were prepared in the same manner.
According to the analysis of related databases, 2-(2-Aminophenyl)acetonitrile, the application of this compound in the production field has become more and more popular.
