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 2817-71-2 as follows. Application In Synthesis of 1-Ethylpyrazole<\/a><\/p>\n

Weigh 0.05 mol of 1-ethyl-1-H-pyrazole (4.8 g) and 0.05 mol of 3-bromopropylamine hydrobromide (10.946 g)Add to a three-necked flask, add 20 mL of absolute ethanol as a solvent, and stir at 80 C for 72 h.After cooling to room temperature, a white solid was separated from anhydrous ethanol, filtered, washed three times with 10 mL of anhydrous ethanol, and dried in a vacuum oven overnight to give a white powder solid.3.15 g of a white powder solid was dissolved in 10 mL of distilled water, the pH was adjusted to about 9 with KOH, and stirred at room temperature for 30 minutes, and then the water in the system was removed with cyclohexane.Pour out cyclohexane.The mixture was extracted with a mixed solution of tetrahydrofuran and methanol, and the inorganic salt solid was removed by filtration, and the obtained liquid was concentrated to give a yellow viscous liquid, yield: 85.16%.<\/p>\n
