Related Products of 117482-84-5, 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. 117482-84-5, name is 3-Chloro-4-fluorobenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 84B 3-chloro-4-(methylamino)benzonitrile A mixture of 3-chloro-4-fluorobenzonitrile (5.2 g, 33 mmol), THF (55 mL), and 40% methylamine in water (25 mL, 290 mmol) in a sealed tube was heated to 65 C. for 1.5 hours, cooled to room temperature. The organic phase was washed with brine, dried (Na2SO4), filtered, and concentrated. The resulting solid was dried for about 16 hours under high vacuum in the presence of P2O5 to provide 6.3 g (95%) of the desired product. MS (DCI/NH3) m/z 184, 186 (M+H+NH3)+; 1H NMR (DMSO-d6) delta 7.72 (d, 1H), 7.55 (dd, 1H), 6.70 (d, 1H), 6.52 (br q, 1H), 2.80 (d, 3H).
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, 3-Chloro-4-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.
