These common heterocyclic compound, 3524-32-1, name is 5-Amino-1,3-dimethylpyrazole, 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. Product Details of 3524-32-1
General procedure: A solution of equimolar amounts (4.5 mmol) of 1,3-dimethyl-1H-pyrazol-5-amine 3 [18] and substituted phenylisocyanates 4a-g in THF (12 mL) was stirred at room temperature for 24 h. The solid residue was filtered, washed with 1 mL of ethyl acetate, and then crystallized from a suitable solvent.
The synthetic route of 5-Amino-1,3-dimethylpyrazole has been constantly updated, and we look forward to future research findings.
