Vorschrift

The above (4.9 g) synthesized in (3) above was dissolved in tetrahydrofuran (60 ml), and N-chlorosuccinimide (2.9 g) was added thereto, followed by reacting the reaction for 6 hours. Thereafter, the solvent was distilled off, and the residue was purified by silica gel chromatography to obtain 3,6-dioxo-4-[3-(2,4-di-t-pentylphenoxy)propylcarbamoyl]-5-chlorobenzonorbornene. (Yield: 5.0 g (95.7 %).
