Abstract:2-(3-(Furan-2-yl)acrylamide)3-phenylpropionicacid(1) was prepared using 2-furanacrylic acid and L-phenylalanine methyl ester hydrochloride as raw materials. The optimum process conditions were obtained after experimental evaluation as followings: preparation of 3-(2-furanyl)acryloyl-l-phenylalanine methyl ester(2) at reaction temperature of 5℃,the material ratio of 2-furanacrylic acid to L-phenylalanine methyl ester hydrochloride and BOP of 0.90∶1.00∶2.00, dichloromethane as reaction solvent, reaction time of 20 h; the optimum temperature for hydrolysis of 20℃, the yield of 1 is 87.53% with apurity of 98.55%. This process had the advandages including lower cost and high yield. It was suitable for industrial production.
Key words:2-(3-(furan-2-yl)acrylamide) 3-phenylpropionic acid; condensation reaction;BOP
