Procedure

84.5 g (0.485 mol) of Compound (k) and 100 ml of ether were cooled to 5° C. or lower. With stirring, 60 ml of an ether solution containing 48.1 g (0.728 mol) of cyclopentadiene, produced by pyrolysis of dicyclopentadiene, were added dropwise thereto. The reaction system was then stirred for one hour, and the solvent was removed by distillation under reduced pressure. By further distillation under reduced pressure, 101 g (86%) of Compound (m) were obtained as a colorless liquid, having a boiling point of 104° to 105° C./0.48 mmHg.
