Reaction Steps

Specifically, 50 g (0.33 mol) of ethyl 2-cyanoacrylate (6a) was dissolved in 200 ml of toluene, and 45 g (0.68 mol) of 1,3-cyclopentadiene (5a) was added dropwise to the solution with cooling temperatures of 35° C. or below. Stirring for one hour and subsequent enrichment yielded 72 g of ethyl 5-cyanobicyclo[2.2.1]hept-2-ene-5-carboxylate represented by Formula (7a) (crude product).
