Cyclopentadiene → Bicyclo[2.2.1]hept-5-ene-2-carboxylic acid, 1,1-dimethylethyl ester

Participants

Reaction Steps

66 g of cyclopentadiene is first put in a reactor and then mixed with 500 g of tetrahydrofuran. 128 g of t-butyl acrylate is added to the reactor. Thereafter, these reactants are subjected to a reaction at a temperature of −30 to 60° C. for 10 hrs with stirring. After the completion of the reaction, the solvent is vaporized in vacuo by use of a rotary evaporator, then vacuum distilled to produce the subject compound: yield is 90%.
