Versuchsvorschrift

To a solution of acetophenone (7.2 g) and 4N-sodium hydroxide solution (14 ml) in ethanol (50 ml) was added 4-acetylamino-3-nitrobenzaldehyde (10.4 g) at ambient temperature under stirring and the resultant mixture was stirred at same condition for 2 hours. To the reaction mixture was added water and precipitate was collected by filtration. The precipitate was suspended in water (300 ml) and the resultant mixture was adjusted to pH 4.0 with 10% hydrochloric acid. The precipitate was collected by filtration and washed with brine and dried to give 3-(4-amino-3-nitrophenyl)-1-phenyl-2-propen-1-one (12.7 g).
