Adding a certain compound to certain chemical reactions, such as: 2075-45-8, name is 4-Bromo-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 2075-45-8, HPLC of Formula: C3H3BrN2<\/a><\/p>\n

To a solution of 4-bromopyrazole (10.0 g, 68.0 mmol) in N,N-dimethylformamide (100 mL) was added dropwise triethylamine (23.7 mL, 170 mmol) under nitrogen atmosphere at room temperature. Trityl chloride (37.9 g, 136 mmol) was added to the reaction solution on an ice bath (0 C.), and stirred for 3 hours at 70 C. Water (400 mL) was added to the reaction solution to precipitate the solids. The precipitated solids were filtered and dried under a reduced pressure. The solids were then azeotropically dried with toluene to obtain the title compound (22.9 g, 87%). 1H-NMR Spectrum (DMSO-d6) delta (ppm): 7.04-7.07 (6H, m), 7.35-7.38 (9H, m), 7.52 (1H, d, J=0.4 Hz), 7.76 (1H, d, J=0.8 Hz).<\/p>\n

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, 4-Bromo-1H-pyrazole, other downstream synthetic routes, hurry up and to see.<\/p>\n
