実験手順

A mixture of the compound (II) (12.0 g), 3,4,5,6-tetarhydrophthalic anhydride (7.56 g) and acetic acid (50 g) was heated at 90° to 95° C. for 7 hours. The reaction mixture was cooled to room temperature, and water (75 g) was added thereto. The precipitated crystals were collected by filtration to give the compound (I) (15.7 g).
