Procedure

This product was prepared by refluxing for four hours, (E)-3-[4-(3-dimethylaminopropenyl)phenyl]acrylic acid, methyl ester with NaOH (0.16 g, 2 equiv.) in 10 mL of MeOH. After evaporation of the solvent in vacuo, treatment with 5 mL of HCl (1N) gave the title compound (0.4 g, 85%) as a gummy orange solid.
