Synthetic Route of 39065-95-7, 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. 39065-95-7, name is 4-(Chlorodifluoromethoxy)aniline belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a reaction flask were added 6-chloro-5-bromonicotinic acid (1.17 g, 4.97 mmol), 4-(chlorodifluoromethoxy)aniline (0.8 g, 4.15 mmol), dissolved with 20 mL anhydrous DMF, 2-(7-aza-1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU, 2.1 g, 5.39 mmol) and N,N-diisopropylethylamine (DIPEA, 534 mg, 4.15 mmol) were added, and the reaction was stirred under nitrogen protection at room temperature for 18 hours. The reaction was diluted with large amount of water, extracted with ethyl acetate for 3-4 times, the organic layers were combined, washed with brine, concentrated, purified by column chromatography, dried in vacuum to afford 1.18 g of a product, yield: 69.5%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-(Chlorodifluoromethoxy)aniline, other downstream synthetic routes, hurry up and to see.
