Abstract:The purpose of this paper is to study the synthetic process of the important pharmaceutical intermediates of 5-hydroxyisoquinoline-7-carboxylic acid and 7-hydroxyisoquinoline-5-carboxylic. The target compound and their isomers were prepared by 3,5-dibromobenzaldehyde via Pomeranz Fritsch synthesis, methylation, palladium catalyzed carbonylation, hydrolysis and demethylation. The purity of the product is 98.2%,97.8% and the yield is 86.3%, 83.7%. The structures of the target compounds were confirmed by 1H NMR, 13C NMR and LC-MS.
Key words:5-hydroxyisoquinoline-7-carboxylic; 7-hydroxyisoquinoline-5-carboxylic; isoquinoline; synthetic
