Further following the procedure described in Example 6B, substituting 3-chloro-1-ethylpropoxy(1,1-dimethylethyl)dimethylsilane (78 g, 0.33 moles) diluted in tetrahydrofuran (100 ml), granular magnesium (24 g, 1.00 moles), tetrahydrofuran (100 ml), 0.1M solution of Li2CuCl4 (1.0 mmole), and 3-chlorocyclopentene (33 g, 0.33 moles) dissolved in tetrahydrofuran (50 ml), one obtains [3-(2-cyclopenten-1-yl)-1-ethylpropoxy](1,1-dimethylethyl)dimethylsilane. The crude product is distilled under reduced pressure leaving a clear yellow oil (21 g, 0.078 moles), BP 69° C./0.1 mm.
