With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.70416-53-4, name is 5-Formylnicotinonitrile, molecular formula is C7H4N2O, molecular weight is 132.12, as common compound, the synthetic route is as follows.COA of Formula: C7H4N2O
INTERMEDIATE 76 PREPARATION OF 5-[(1E)-3-OXOPROP-1-EN-1-YL]PYRIDINE-3-CARBONITRILE A mixture of 5-formylpyridine-3-carbonitrile (1.82 g, 13.78 mmol) and (formylmethylene)triphenylphosphorane (4.28 g, 14.06 mmol) in DMSO (15 mL) was stirred overnight at 120 oC under a nitrogen atmosphere. After being cooled to room temperature, the reaction mixture was diluted with water (30 mL) and extracted with EtOAc (3 x 20 mL). The combined organic layers were dried over Na2SO4 and concentrated under reduced pressure. The crude product was purified by column chromatography (EtOAc-petroleum ether, 1:3) to afford the title compound (490 mg, 22%) as a white solid.1H NMR (300 MHz, CDCl3) delta 9.79 (d, J = 7.2 Hz, 1H), 8.99 (d, J = 2.1 Hz, 1H), 8.92 (d, J = 2.1 Hz, 1H) 8.14 (m, 1H), 7.52 (d, J = 15.6 Hz, 1H), 6.87-6.79 (m, 1H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,70416-53-4, 5-Formylnicotinonitrile, and friends who are interested can also refer to it.
