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. 67310-56-9, name is 1-(5-Hydroxypyridin-2-yl)ethanone, the common compound, a new synthetic route is introduced below. Recommanded Product: 1-(5-Hydroxypyridin-2-yl)ethanone
A mixture of Example 28A (0.1 g, 0.235 mmol), l-(5-hydroxypyridin-2-yl)ethanone (0.065 g, 0.471 mmol), potassium carbonate (0.065 g, 0.471 mmol) and potassium iodide (2.73 mg, 0.016 mmol) in acetone (2.0 mL) was stirred at 140 C (0-450 W) in a Biotage Initiator microwave reactor for 45 minutes. The suspension was filtered, and the filtrate was concentrated. This residue and NaBH^ (0.089 g, 2.35 mmol) in methanol was stirred at ambient temperature overnight. The reaction mixture was concentrated, and the residue was purified by HPLC (10-85% acetonitrile in 0.1% trifluoroacetic acid/water at 25 mL/minute on aPhenomenex Luna CI 8 5 mupiiota 100 A AXIA column (250 mm x 21.2 mm)) to give 59 mg of the title compound as a white solid.JH NMR (400 MHz, DMSO-<) delta ppm 8.74 (d, / = 26.6 Hz, 2H), 8.30 (d, / = 2.8 Hz, 1H), 7.81 - 7.60 (m, 2H), 7.47 (t, / = 8.9 Hz, 1H), 7.05 (dd, / = 11.4, 2.8 Hz, 1H), 6.83 (ddd, / = 9.0, 2.9, 1.2 Hz, 1H), 4.85 (q, / = 6.5 Hz, 1H), 4.61 (s, 2H), 4.46 (s, 2H), 2.25 (s, 6H), 1.37 (d, / = 6.5 Hz, 3H). MS (ESI+) m/z 464.0 (M+H)+.
The synthetic route of 67310-56-9 has been constantly updated, and we look forward to future research findings.
