Adding a certain compound to certain chemical reactions, such as: 1260243-04-6, name is Ethyl 5-amino-1H-pyrazole-4-carboxylate, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1260243-04-6, Safety of Ethyl 5-amino-1H-pyrazole-4-carboxylate<\/a><\/p>\n

General procedure: Method I. A mixture of Py (4.4 ml) and AcOH (3.0 ml) was stirred and treated by the addition of 5-aminoazole1a-h (0.01 mol) and (2E)-(3-morpholin-4-yl)-acrylonitrile (2) (1.38 g, 0.01 mol). The obtained mixture was refluxed at 150C for 5 h. After refluxing, the mixture was cooled. The precipitate that formed was filtered off, washed with a small amount of EtOH, and dried. Method II. A solution (or suspension) of the appropriate aminoazole 1a-h (0.01 mol) in solvent (15 ml) (EtOH in the case of compound 3a, dioxane in the case of compounds 3b-h) was stirred at 50C and treated by adding 3,3-diethoxypropionitrile (4) (1.5 ml, 0.01 mol), then 36% HCl solution (0.86 ml, 0.01 mol). The reaction mixture was refluxed for 2.5-3 h, the suspension (or solution) was cooled to room temperature, and the target product was isolated by the method indicated for each particular compound.<\/p>\n
