Procedure

A mixture of 2-cyanoethyl hexanoylacetate (21.1 g, 100 mmol), 4-nitrobenzaldehyde (16.6 g, 110 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 resulting white precipitate was filtered and dried in the air. The product, 2-[(4-nitrophenyl)methylene]-3-oxooctanoic acid 2-cyanoethyl ester was obtained as a white powder (25.2 g, 73% yield).
