Application of 77326-36-4, 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. 77326-36-4, name is 2-Amino-6-fluorobenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Under argon, 2-amino-6-fluorobenzonitrile (300 mg, 2.20 mmol) was dissolved in pyridine (3.6 ml, 44 mmol), 4-dimethylaminopyridine (2.69 mg, 22.0 muiotaetaomicron) and 3-Chlorobenzoylchlorid (501 mg, 2.86 mmol) were added and the mixture was stirred at room temperature for 16 h. The mixture was diluted with ethyl acetate, washed with water and brine, and dried over magnesium sulfate. Concentration in vacuo and purification by preparative HPLC afforded the title compound. The obtained amount was 401 mg (100% Purity, 66 % of theory). LC-MS (Method 1): Rt = 0.97 min; MS (ESIPos): m/z = 275 [M+H]+
The synthetic route of 2-Amino-6-fluorobenzonitrile has been constantly updated, and we look forward to future research findings.
