Reaction Steps

In 600 ml of benzene was dissolved 125.0 g of 2-ethylbicyclo[2.2.1]heptan-2-ol in endo-form. To the solution was added 8.5 g of p-toluenesulfonic acid monohydrate. This reaction mixture was heated, agitated under reflux for 6 hours while removing water, and subjected to conventional post-treatment. The resulting oily substance was purified by silica gel column chromatography, obtaining 85.9 g of 2-ethylidenebicyclo[2.2.1]heptane. The yield was 78.8%.
