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

Participants

Reaction Steps

In a reactor, cyclopentadiene (66 g) and tetrahydrofuran solvent (500 g) were charged, and the mixture was stirred homogeneously. To the reaction mixture, tert-butyl acrylate (128 g) was added, and the resultant mixture was stirred at a temperature between −30° C. and 60° C. for about 10 hours to carry out the reaction. When the reaction was completed, the solvent was removed by using a rotary evaporator, and the residue was distilled under reduced pressure to obtain 176 g (yield: 90%) of tert-butyl 5-norbornene-2-carboxylate represented by chemical formula VIIa.
