A mixture of 4'-amino-2'-chlorovaleranilide (2.27 g., 0.01 mole) anti-tricyclo[4.2.2.02,5 ]dec-3,9-diene-endo7,endo-8-dicarboxylic anhydride (2.02 g., 0.01 mole) and pyridine (20 ml.) is heated under reflux for twenty-four hours. The solvent is removed in vacuo and the residue (4.35 g., m.p. 120°-136° C.) is recrystallized from butyl chloride to give N-(3-chloro-4-valeramidophenyl)-antitricyclo[4.2.2.02,5 ]dec-3,9-diene-endo-7,endo-8-dicarboximide, m.p. 157.5°-159° C.
