A mixture of 5.00 g of trans-β-benzoylacrylic acid, 1.67 ml of n-propanol and 1.05 g of sulfuric acid was stirred at 100° C. for 1.5 hours. A pressure was gradually reduced with the aspirator and n-propanol was distilled away for 15 minutes. After a pressure was finally reduced to 20 mmHg, the resultant was stirred at 100° C. for 10 minutes and then cooled, followed by the procedure as in Example 1 to give 5.78 g of n-propyl trans-β-benzoylacrylate.
