The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 174669-74-0, name is 2-Fluoropyridin-3-ol. This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C5H4FNO
Iodomethane 1.7 mL (27 mmol) and cesium carbonate 4.3 g (13. mmol) were added to a DMSO (20 mL) solution of 2-fluoropyridin-3-ol 1.0 g (8.8 mmol), and the mixture was stirred at 60C for 1 hour. After the completion of the reaction, a saturated aqueous ammonium chloride solution was added to the reaction mixture, and followed by extraction with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under reduced pressure to give the title compound 1.1 g (8.7 mmol, yield 99%) as a white solid. 1H-NMR spectrum (400MHz, DMSO-d6) delta:7.76 – 7.69 (m, 1H), 7.65 (ddd, J = 1.5, 8.0, 10.7 Hz, 1H), 7.31 (ddd, J = 0.9, 4.8, 8.0 Hz, 1H), 3.88 (s, 3H).
With the rapid development of chemical substances, we look forward to future research findings about 174669-74-0.
