Reaction Steps

o-Nitrobenzaldehyde (43.4 g, 0.29 mole) and acetoacetic isopropylamide (40.0 g, 0.29 mole) are dissolved in benzene (150 ml) and thereto are added piperidine (1.15 ml) and acetic acid (3.45 ml), and the mixture is refluxed and the produced water is removed. After the stoichiometic amount of water is distilled off, the reaction is stopped. After the reaction, the solvent is distilled off under reduced pressure, and the residue is recrystallized from ethanol to give the title compound (62.7 g, yield 78.4%) as colorless prisms, m.p. 132°-135° C.
