Application of 2817-71-2, A common heterocyclic compound, 2817-71-2, name is 1-Ethylpyrazole, molecular formula is C5H8N2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
3.102 g (18 mmol) of hydrobromic acid was gradually added dropwise to 1.44 g (15 mmol) of 1-ethylpyrazole,The reaction was stirred at 40 ~ 50 for 15 ~ 25h to ensure that all the substrates reacted completely, then cyclohexane was used as a water-carrying agent to remove the moisture therein,Further washing with ethyl acetate gave 1-ethylpyrazole hydrobromide as a pale yellow liquid (yield> 90%).
The synthetic route of 2817-71-2 has been constantly updated, and we look forward to future research findings.
