【Abstract】 Under microwave irradiation, two benzoxazolyl-substituted pyridine were synthesized by condensation of o-aminophenol and pyridine carboxylic acid catalyzed by polyphosphoric acid.The optimum reaction condition is as follows: microwave power 450 W and microwave irradiation time 4 min. Compared with the conventional reaction,the reaction time was shortened obviously and the yield was satisfactory.更多还原
