Reaction Steps

To a solution of 4-hydroxybenzaldehyde (31.7 g, 0.26 mol) and ethyl benzoylacetate (45.5 ml, 0.26 mol) in EtOH (45 ml) under an argon atmosphere was added piperidine (2.6 ml, 0.026 mol) and acetic acid (3 drops). After stirring at room temperature overnight, the resulting solid mixture was treated with hot EtOH (700 ml), and then allowed to cool. The crystals which formed were collected by filtration to afford the title compound (61.0 g, 79%).
