Adding a certain compound to certain chemical reactions, such as: 155600-99-0, name is 3,5-Dibromo-1-methyl-4-nitro-1H-pyrazole, 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 155600-99-0, SDS of cas: 155600-99-0
Production example 8 3-bromo-5-tert-butylamino-1-methyl-4-nitropyrazole 1.5 g (5.26 mmoles) of 3,5-dibromo-1-methyl-4-nitropyrazole are heated in a solution of 20 ml tert-butylamine in 30 ml ethanol for 20 hours at boiling temperature. After cooling, the reaction mixture is poured on 150 ml water, the separated product is filtered and washed with 100 ml water. After vacuum drying, 1.14 g (78 percent of theory) of 3-bromo-5-tert-butylamino-1-methyl-4-nitropyrazole are obtained in the form of pale yellow flakes with a melting point of 75 to 77 C. 1 H-NMR (60 MHz, DMSO-d6):=5.35 (s; 1H; –NH; exchanges with D2 O), 3.75 (s; 3H; N–CH3) and 1.20 ppm (s; 9H; –C(CH3)3). MS (70 eV): m/e=277 (M+).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3,5-Dibromo-1-methyl-4-nitro-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
