1-Isopropyl-1H-pyrazole-5-boronic acid, pinacol ester Chemical Properties,Uses,Production

Synthesis

1-Isopropyl-1H-pyrazole-5-boronic acid, pinacol ester could be synthesized through the reaction of 1-isopropyl-1H-pyrazole with 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane. Tetrahydrofuran could used as an organic solvent. The crude product added n-hexane, heated to 40°C to dissolve the system, cooled to -20°C, stirred and crystallized, and filtered. Vacuum drying to obtain the target compound 1-Isopropyl-1H-pyrazole-5-boronic acid, pinacol ester, with a yield of 77% and a purity of 99.3%.
