実験手順
A solution of 4-carboxybenzaldehyde (38.44 g) in nitroethane (360 ml) and butylamine (2 ml) was heated at reflux for 2 hours with azeotropic distillation of water using a Dean and Stark apparatus The solution was cooled to room temperature and the resulting solid was collected and recrystallised from isopropanol (250 ml) with hot filtration to give 1-(4-carboxyphenyl)-2-nitropropene (31.57 g) in the form of a yellow crystalline solid, m.p. 212°-214° C.
