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, Computed Properties of C6H9N3O2<\/a><\/p>\n

Example C.22 5-(4-Chloro-phenyl)-pyrazolo[1,5-a]pyrimidine-3-carboxylic acid; a. A mixture of ethyl 3-(4-chloro-phenyl)-3-oxo-propionate (18.1 g, 0.080 mol) and ethyl 5-amino-1H-pyrazole-4-carboxylate (13.7 g, 0.088 mol) was stirred at for 3 h 160 C. Ethyl acetate (40 mL) and hexane (40 mL) were successively added to the cooled mixture and stirring was continued at 0 C. for 0.5 h. The crystals were isolated by filtration and triturated for 1.2 h with 0.2 N HCl (80 mL). The solid was filtered off, washed with water and dried to give ethyl 5-(4-chloro-phenyl)-7-hydroxy-pyrazolo[1,5-a]pyrimidine-3-carboxylate (13.3 g, 52%). White solid. MS (ISN) 316.3 [(M-H)-]; mp 190-192 C.<\/p>\n
