Abstract:1-Alkyl-pyrazole acid is an important intermediate for the synthesis of many biologically active compounds. The target compound was prepared in overall yield of 27.4% starting from 1H-pyrazole via methylation with trimethyl phosphate,converting into boronic acids with trimethyl borate after reaction with n-butyl lithium,and condensation with pinacol. The process conditions were optimized for the synthesis and purification of intermediate 3. The structure of
target compound was characterized by 1H NMR. |
Key words:pinacol 1-methyl-1H-pyrazole boronate;synthesis;pinacol |
