Reaction Steps
A mixture of indan-1-one (20.0 g), 4-nitrobenzaldehyde (27.0 g), glacial acetic acid (3.0 g) and piperidine (3.06 g) was heated at 95° C. under nitrogen for 3.5 h. The mixture was cooled to 20° C. and filtered to give a solid which was recrystallized from industrial methylated spirit to give 2-(4-nitrobenzylidene)indan-1-one.
