Abstract
3-Quinolinecarboxylic acid methyl ester was synthesized from quinoline-2,3-dicarboxylic acid in steps of decarboxylation,chlorization and alcoholysis in an overall yield of 83.5%.The structure of the target compound was identified by IR and 1H NMR.Its melting point was 74~75℃.The mechanism of decarboxylation was discussed.
