Application of 1453-58-3<\/a>, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1453-58-3 as follows.<\/p>\n

To a solution of 3-methyl-1H-pyrazole (10.99 g, 134 mmol) in N,N-dimethylformamide (100 ml) at 0\u00b0 C. was added sodium hydride (3.71 g, 154 mmol, 60percent dispersion). The reaction was stirred at 0\u00b0 C. for 2 hours. 3-Fluoropyridine (10.0 g, 103 mmol) was added, and the reaction was stirred at 100\u00b0 C. overnight. The reaction was cooled to room temperature and water was added slowly. The mixture was extracted with dichloromethane and the combined organic phases were washed with brine, concentrated and chromatographed (0-100percent ethyl acetate\/hexanes) to afford 3-(3-methyl-1H-pyrazol-1-yl)pyridine (8.4 g, 52.77 mmol, 51.2percent) and 3-(5-methyl-1H-pyrazol-1-yl)pyridine (1.0 g, 6percent). Analytical data of both products is consistent with that reported under Example 6, Step 1.<\/p>\n

According to the analysis of related databases, 1453-58-3, the application of this compound in the production field has become more and more popular.<\/p>\n
