Procedure

A cinnamic acid is first prepared by reacting a benzaldehyde with malonic acid in pyridine and piperidine. The cinnamic acid is then reacted with thionyl chloride to produce a cinnamoyl chloride derivative. The PECN is finally synthesized by reacting PECN with the cinnamoyl chloride derivative in an inert solvent (such as chloroform, nitrobenzene, chlorobenzene, or the like). The reaction mixture is diluted with methanol, filtered, dried in a vacuum, and milled by a vibrating mill, whereupon the PECN is obtained.
