Abstract:Title compound was prepared starting from 3,4,5,6-tetrafluorophthalic acid via hydrolysis,decarboxylation,methylation,acylation,condensation,decarboxylation,propylamine esters,cyclization,boron esterification and condensation with piperazine in an overal yield of 18.3%. The reaction conditions were optimized,which are adaptable to industrial scale-up.
Key words:3,4,5,6-tetrafluorophthalic acid;synthesis;optimization
