77% | In 5,5-dimethyl-1,3-cyclohexadiene; at 180℃; for 2h;Inert atmosphere; | 50 g (130.05 mmol) of 2,3,4,5-tetraphenylcyclopenta-2,4-diene and 21.05 g (143.05 mmol) of Intermediate E-2 were put in a 250 mE flask, and 150 ml of xylene was added thereto. The mixture was heated and stirred under a nitrogen flow at 180 C. After 2 hours, a reaction was completed. Afier completing the reaction, the reactant was slowly dropped to 1000 mE of methanol to produce a solid. Themixture having the solid was stirred for 2 hours and then,filtered to obtain Intermediate E-3 (50.28 g, 77%).calcd.
