Reaction Steps

The solution of 2-(3,4-dimethyl-1,3-cyclopentadien-1-yl)-5-methylfuran (3.2 g, 20 mmol) in Et2O (40 mL) was cooled to −20° C. and BuLi (8 mL 2.5N in hexane, 20 mmol) was added dropwise. Suspension obtained was stirred 1 h at room temperature, cooled again to −20° C., and ZrCl4(THF)2 (3.77 g, 10 mmol) was added. After 16 h of stirring, the precipitate was filtered off, dissolved in dichloromethane, solution was filtered and solvent was evaporated. Residue was washed with Et2O, pentane and dried in vacuo giving 0.6 g of product as pure form. Filtrate was concentrated and 1.3 g of complex was obtained as mixture of isomers (1:1 ratio). (total yield 38%).
