Chemical Properties

white to light yellow crystal powde

Uses

5-Amino-1,3-dimethylpyrazole may be used in the preparation of:

5-benzamido-1,3-dimethylpyrazole
diethyl 2-{[(1,3-dimethyl-1H-pyrazol-5-yl)amino]methylene}malonate
5-amino-1,3-dimethyl-4-phthalidylpyrazole
(E)-N-(3,7-dimethylocta-2,6-dienyl)-1,3-dimethyl-1H-pyrazol-5-amine analog(LQFM002)
4-isopropyl-1,3-dimethyl-1H-pyrazolo[3,4-b]pyridin-6-ol

General Description

5-Amino-1,3-dimethylpyrazole undergoes cyclocondensation with ethyl acetoacetate to form the corresponding tetrahydropyrazolopyridine derivatives.

Synthesis

1118-61-2

60-34-4

3524-32-1

To a solution of 3-aminobut-2-enenenitrile (16.5 g, 0.2 mol) in n-pentanol (40 mL) was slowly added methylhydrazine (12.9 g, 0.28 mol). The reaction mixture was heated to reflux and kept for 3 hours. Upon completion of the reaction, n-pentanol and excess methylhydrazine were removed by distillation under reduced pressure. The resulting beige precipitate was dissolved in heptane (150 mL) and filtered through a sintered funnel. The filtrate was dried under vacuum at 40 °C to afford 5-amino-1,3-dimethylpyrazole as a beige solid (13.5 g, 60.4% yield).
