Reaction Steps
Piperidine (0.5ml) was added to a solution of paranitrobenzaldehyde (7.5g, 0.05 moles) and ethyl acetoacetate (6.5g, 0.05 moles) and stirred at room temperature for 48 hrs. Ethyl ether (50ml) was added and stirring continued for 7 days. After removal of the ethyl ether by rotary evaporator the titled products were separated and purified by silica gel chromatography. The structure assignments were supported by NMR, infrared and uv spectra and elemental analysis (263.2).
