Reaction Steps

A suspension of 4-nitrobenzaldehyde (16.61 g, 110 mmol), 2-cyanoethyl butyrylacetate (19.34 g, 100 mmol), piperidine (430 mg, 5.00 mmol) and acetic acid (300 mg, 5.00 mmol) in 350 ml of 2-propanol was stirred at room temperature for 48 hrs. The reaction mixture was filtered and resulting solid was air dried to give 2-[(4-nitrophenyl)methylene]-3-oxohexanoic acid 2-cyanoethyl ester as a white powder (31.0 g, 95%).
