Reference of 423768-52-9,Some common heterocyclic compound, 423768-52-9, name is 3-(Aminomethyl)-1,5-dimethylpyrazole, molecular formula is C6H11N3, 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.
To a solution of ethyl 2-(2-amino-4,6-dichloropyrimidin-5-yl)acetate (200 mg, 0.80 mmol) in EtOH (30 mL) was added (l,5-dimethyl-lH-pyrazol-3-yl)methanamine (300 mg, 2.40 mmol) and Et3N (400 mg, 3.96 mmol). The resulting solution was refluxed for 3 hours. The reaction mixture was concentrated under vacuum. The residue was purified on a silica gel column with DCMrMeOH (50:1), resulted in 0.25 g (31%) of ethyl 2-(2-amino-4-chloro- 6-((l,5-dimethyl-lH-pyrazol-3-yl) methylamino)pyrimidin-5-yl)acetate as a yellow solid
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-(Aminomethyl)-1,5-dimethylpyrazole, its application will become more common.
