A mixture of ortho-hydroxyaryl aldehyde (20 mmol), Meldrum's acid (2.89 g, 20 mmol), piperidinium acetate (58 mg, 0.4 mmol) and ethanol (10 mL) was stirred at room temperature for 20 min, and then refluxed for 2 h. The reaction mixture was allowed to cool down to room temperature, followed by chilling in an ice bath for 1 h. The crystallized product was filtered, washed three times with ethanol, and dried in vacuo.
