반응 단계
The Diels-Alder adduct from cyclopentadiene and maleic anhydride, endo-cis-5-norbornene-2,3-dicarboxylic anhydride, m.p. 165° C., was heated at 220° C. for 4 hours. On cooling the product solidified with a melting point of 101° C. The crude reaction product was recrystallized from benzene three times to isolate exo-cis-5-norbornene-2,3-dicarboxylic anhydride, m.p. 141° C., in 25% yield.
