Electric Literature of 694-31-5,Some common heterocyclic compound, 694-31-5, name is 1,5-Dimethyl-1H-pyrazole, molecular formula is C5H8N2, 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.
In this example, the preparation of 1,5-dimethylpyrazole hydrobromide is as follows:1.442 g (15 mmol) of 1,5-dimethylpyrazole and 3.102 g (18 mmol) of hydrobromic acid were respectively added to 100 mL of three neck Bottle, stirring 15 ~ 30h; After the reaction, the addition of water, the product was washed with ethyl acetate and dried to give a white solid 1,5-dimethylpyrazole hydrobromide ionic liquid, a yield of 70%
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1,5-Dimethyl-1H-pyrazole, its application will become more common.
