1,3-Dimethyl-1H-pyrazol-5-amine Use and Manufacturing
To a solution of 3-aminocrotononitri.e (16.5 g, 0.2 mo.) in n-pentanoi (40 mL) was added methylhydrazine (12, 9 g, 0.28 moi). The solution was maintained at reflux for 3 hours. The n-pentanol and the excess methylhydrazine were subsequently distilled off under reduced pressure, The beige precipitate obtained was taken up in heptanes (150 mL), filtered on a sinter funnel and then dried under vacuum at a temperature of 40 °C to afford the product 1 , 3-dimethyl-1 H-pyrazo.-5-amine as a beige solid (13.5 g, yield 60.4 percent).Under nitrogen atmosphere, to a 500 mL of round bottom flask were added 2-cyanoacetone (8 g, 0.096mol) and 200 mL of anhydrous ethanol. 2-cyanoacetone was dissolved with stirring at room temperature. Methylhydrazine (4.43 g, 0.096 mol) was added to obtain a resultant mixture. The mixture was slowly warmed and refluxed. After reacting for 3 hr, the solvent was rotary-evaporated to obtain a product as oil. The product was purified by column chromatography to give 4.2 g of the title compound. MS (ESI): m/z 112 (M+H)
