Reference of 1659-31-0, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1659-31-0, name is Dipyridin-2-yl carbonate. A new synthetic method of this compound is introduced below.
Under nitrogen atmosphere, to a stirred mixture of (4-cyclohexylphenyl)-methanol (0.3 g, 1.58 mmol) in dry CH2C12 (2 mL), DMAP (0.019 g, 0.16 mmol) and di-2-pyridyl- carbonate (0.41 1 g, 1.90 mmol) were added. The reaction mixture was left to react at rt for 15 h, then diluted with CH2C12 and washed first with a saturated NH4C1 solution (3.0 mL) and subsequently with a saturated NaHC03 solution (3X3 mL). The organic fraction was dried over Na2S04, filtered and concentrated to dryness to afford a colorless oil (0.464 g, 95%), as a mixture (ratio 1.8: 1) of (4-cyclohexylphenyl)-methyl-2-pyridyl carbonate and (4- cyclohexylphenyl)-methy 1-2 -oxopyridine-1 -carboxylate. The mixture of isomers was not separated and used in the next step without any further purification. MS (ESI) m/z 350 [M- K]+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1659-31-0, Dipyridin-2-yl carbonate, and friends who are interested can also refer to it.
