Reaction Steps

A solution of 8.6 g. ethyl 4-aminohydrocinnamate, 9.77 g. 5-octyl-2-thiophenecarboxaldehyde and a few crystals of 2,4-dinitrobenzenesulfonic acid in 250 ml. toluene is refluxed under a Dean-Stark trap for 17 hours, whereupon the theoretical amount (0.8 ml.) water has been collected. The toluene is evaporated to yield ethyl 3-[4-(5-octyl-2-thienylideneamino)phenyl]propionate as a crystalline mass.
