Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 84547-86-4, name is 4-Bromo-1-methyl-1H-pyrazole-3-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 4-Bromo-1-methyl-1H-pyrazole-3-carboxylic acid

A mixture of methyl 4-bromo-1-methyl-1H-pyrazole-3-carboxylic acid (1eq), 4,4,4′,4′,5,5,5′,5′- octamethyl-2,2′-bi(1,3,2-dioxaborolane) (1 eq), KOAc (2 eq) and Pd(dppf)Cl2 (5 mol%) in 1,4- dioxane (10 mL) was stirred at 100 oC overnight. The precipitate was removed by filtration and the filtrate was used for next step without further purification. ESI-MS (m/z): 267.20 [M+1]+.
