Related Products of 13600-47-0, 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.13600-47-0, name is 5-Aminonicotinonitrile, molecular formula is C6H5N3, molecular weight is 119.12, as common compound, the synthetic route is as follows.
(5)-4-Bromo-2,2-difluoro-7-((trifluoromethyl)sulfonyl)-2,3-dihydro-lH-inden- l-ol (23 mg, 0.060 mmol) was dissolved in 1,4-dioxane (0.20 mL) and treated with 3- pyridinecarbonitrile, 5-amino- (8.6 mg, 0.070 mmol), cesium carbonate (27.5 mg, 0.080 mmol), palladium (II) acetate (0.68 mg, 0.003 mmol), and Xantphos (3.5 mg, 0.010 mmol). After cooling, the mixture was diluted with water and ethyl acetate then separated. This mixture didn’t separate well and there was insoluble yellow solid present, which was removed by filtration. The aqueous was washed with ethyl acetate and the combined organics were washed with saturated NaHC03, saturated NaCl, dried over Na2S04, and concentrated in vacuo to a dark residue. The crude material was chromatographed on Si02 eluting with a gradient of ethyl acetate / hexanes. The product was recovered as light tan solid, (12 mg, 47%). LCMS ESI (+) m/z (M+H) 420; 1H NMR (400 MHz, CDC13 plus CD3OD): delta 8.66 (s, 1H), 8.60 (s, 1H), 7.79-7.75 (m, 2H), 7.22-7.20 (m, 1H), 5.30 (d, 1H), 3.92-3.90 (m, 1H), 3.46-3.32 (m, 1H), 3.31-3.21 (m, 1H).
Statistics shows that 13600-47-0 is playing an increasingly important role. we look forward to future research findings about 5-Aminonicotinonitrile.
