Uses	5-amino-1, 3-dimethylpyrazole is a heterocyclic derivative that can be used as an intermediate in organic synthesis.
Preparation	There are many ways to synthesize 5-amino -1, 3-dimethylpyrazole: Condensation with Mannich base and methylhydrazine [1]. Add methylhydrazine to a condensation pot, add 3-amino croton nitrile at 90-95 ℃, add it in about 30-40min, after condensation, the pH is 2.5-3, the temperature is reduced to 45 ℃ after reaction, wash with water to neutral or acidic, and dry to obtain the finished product.
