Adding a certain compound to certain chemical reactions, such as: 38275-55-7, 5-Fluoropyrimidine-2-carbonitrile, 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, Computed Properties of C5H2FN3, blongs to pyrimidines compound. Computed Properties of C5H2FN3
Method 12; N-(l-(5-Fluoropyrimidin-2-yl)vinyl)acetamide; 5-Fluoropyrimidine-2-carbonitrile (Method 6, 1.0 g, 8.1 mmol) in THF (10 ml) was added a solution of MeMgBr (3.3 ml, 9.75 mmol) in ether drop wise at 0 0C. After addition, the reaction was warmed to room temperature, stirred at room temperature for 1 hour and then diluted with DCM (10 ml). Acetic anhydride (1.23 ml, 13.0 mmol) was added in one portion. The reaction was stirred at room temperature for 1 hour and 40 0C for 1 hour. Saturated sodium bicarbonate solution (10 ml) was added and extracted with EtOAc (2×20 ml). The combined organic was dried over sodium sulfate. After removal of solvent, the resulted residue was purified by column chromatography (hexane-EtOAc = 2.5 : 1) to give the title compound as a white solid (0.38 g, 26%). 1H nuMR (400 MHz) 9.34 (s, IH), 8.95 (s, 2H), 6.25 (s, IH), 6.03 (s, IH), 2.11 (s, 3H). MS: Calcd.: 181; Found: [M+H]+ 182.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,38275-55-7, 5-Fluoropyrimidine-2-carbonitrile, and friends who are interested can also refer to it.
