実験手順
A mixture of 9.4 g of stilbene-4-aldehyde thus-obtained, 10.6 g of malonic acid, 30 ml of pyridine and 3 ml of piperidine was reacted on a steam bath at 100° C. for 4 hours. After the completion of the reaction, the mixture was poured into an exess amount of water and the precipitate thus-obtained was collected and recrystallized from acetic acid to obtain 11.0 g of p-styryl cinnamic acid.
