New learning discoveries about 2-Fluoronicotinic acid

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. 393-55-5, 2-Fluoronicotinic acid, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 393-55-5, Adding some certain compound to certain chemical reactions, such as: 393-55-5, name is 2-Fluoronicotinic acid,molecular formula is C6H4FNO2, 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 393-55-5.

Thionyl chloride (0.43 mL, 5.87 mmol) was added to a slurry of 2-fluoronicotinic acid (9, 0.69 g, 4.89 mmol) and N,N-dimethylformamide (0.1 mL, catalytic amount) in benzene (60 mL) at room temperature under nitrogen, after which the mixture was heated at reflux for 3 h. The solvent was removed under reduced pressure to provide an amber oil that was dissolved in 1,4-dioxane (40 mL) under nitrogen. The solution was treated with sodium borohydride (0.38 g, 10.0 mmol) and the mixture was stirred at room temperature for 24 h. The suspension was diluted with saturated NaHCO3 solution (200 mL) and extracted with diethyl ether (3×200 mL). The combined organic extracts were dried over Na2SO4, filtered and the solvents were removed under reduced pressure to provide the title compound: 1H NMR (300 MHz) 8.13 (d, J=3.7 Hz, 1H), 7.93-7.88 (m, 1H), 7.24-7.19 (m, 1H), 4.78 (s, 2H), 2.14 (bs, 1H) ppm.

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. 393-55-5, 2-Fluoronicotinic acid, other downstream synthetic routes, hurry up and to see.
