Synthetic Route of 55304-75-1, Adding some certain compound to certain chemical reactions, such as: 55304-75-1, name is 2,6-Dichloro-3-(trifluoromethyl)pyridine,molecular formula is C6H2Cl2F3N, 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 55304-75-1.
Nine separate sealed tubes, each containing a mixture of 2,6-dichloro-3-(trifluoromethyl)pyridine (10.0g, 46.3 mmol) and ammonium hydroxide (91 g, 100 mL, 2600 mmol) were stirred at 100 C. for 12 h. After cooling to rt, the contents of all of the sealed tubes were combined and the solvents were concentrated in vacuo. Purification of the (FCC, SiO2; 5-20% EtOAc/petroleum ether) afforded the title compound as a colorless oil (57 g, 66%), which solidified upon standing. MS (ESI): mass calcd. for C6H4ClF3N2, 196.0; m/z found, 196.8 [M+H]+. 1H NMR (400 MHz, CDCl3) delta 7.69 (d, J=8.0 Hz, 1H), 6.42 (d, J=8.4 Hz, 1H), 5.01 (br s, 2H).
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. 55304-75-1, 2,6-Dichloro-3-(trifluoromethyl)pyridine, other downstream synthetic routes, hurry up and to see.
