Adding a certain compound to certain chemical reactions, such as: 696-42-4, 5-Fluoronicotinonitrile, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, HPLC of Formula: C6H3FN2, blongs to pyridine-derivatives compound. HPLC of Formula: C6H3FN2
General procedure: (Reference Example 35) 5-[4-(5-Amino-1H-pyrazol-3-yl)piperidin-1-yl]pyridine-3-carbonitrileThe title compound (0.167 g, yield: 37%) was obtained through reaction in the same way as the method described in Reference Example 34 using 5-fluoropyridine-3-carbonitrile (0.204 g, 1.67 mmol) instead of 3,6-dichloropyridazine. 1H-NMR (400 MHz, DMSO-d6) delta: 11.13 (1H, brs), 8.59 (1H, d, J = 3 Hz), 8.28 (1H, d, J = 2 Hz), 7.78 (1H, dd, J = 3 Hz, 2 Hz), 5.20 (1H, brs), 4.45 (2H, brs), 3.94-3.87 (2H, m), 2.93-2.85 (2H, m), 2.73-2.64 (1H, m), 1.94-1.87 (2H, m), 1.65-1.55 (2H, m).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,696-42-4, 5-Fluoronicotinonitrile, and friends who are interested can also refer to it.
