Application of 1659-31-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 1659-31-0, name is Dipyridin-2-yl carbonate, molecular formula is C11H8N2O3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a suspension of sodium hydride, 60% in mineral oil (185 mg, 4.63 mmol) in THF (20 mL) was added 3-methyltetrahydrofuran-3-ol (394 mg, 3.86 mmol) at 0 C. After stirring 30 min, the solution was transferred to a solution of di(pyridin-2-yl)carbonate (834 mg, 3.86 mmol) in THF (20 mL) through a cannula. The formed slurry was stirred at 0 C. for 30 min. The slurry was warmed to rt and stirred for 2 h. The reaction was diluted with EtOAc, washed with brine, dried over MgSO4, filtered, concentrated to give a residue that was purified by Biotage (5-40% EtOAc:Hex) to afford the desired product 3-methyltetrahydrofuran-3-yl pyridin-2-yl carbonate (334 mg, 38.8% yield) as an oil.1H NMR (400 MHz, CHLOROFORM-d) delta 8.48-8.29 (m, 1H), 7.91-7.73 (m, 1H), 7.29-7.25 (m, 1H), 7.16-7.12 (m, 1H), 4.23 (d, J=10.3 Hz, 1H), 4.02 (td, J=8.5, 7.2 Hz, 1H), 3.95 (td, J=8.4, 4.5 Hz, 1H), 3.76 (d, J=10.3 Hz, 1H), 2.58-2.47 (m, 1H), 2.11-2.02 (m, 1H), 1.76 (s, 3H).
According to the analysis of related databases, 1659-31-0, the application of this compound in the production field has become more and more popular.
