実験手順
Using a procedure similar to that described in Example D, 33 g of 3-nitroacetophenone and 26.2 g of cinnamaldehyde in 200 ml of ethanol were condensed in the presence of 10 ml of a 5% strength NaOH solution to give 38 g (71% of theory) of 1-(3-nitrophenyl)-5-phenyl-2,4-pentadien-1-one of melting point 127°-129° C.
