Procedure

In the presence of 0.3 g of paratoluenesulfonic acid, 20 g (0.16 mol) of cyclooctanone and 27 g (0.18 mol) of ethyl orthoformate were stirred at room temperature overnight. The resultant mixture was heated at 100° C. for 15 hours and distilled under reduced pressure to give 10.9 g (45% yield) of 1-ethoxycyclooctene having a boiling point of 97.5° to 98.5° C./25 mmHg.
