The procedure of synthesizing Compound 34a was repeated, except that 3-methylpentan-3-ylmaganesium chloride THF solution (100 mL), which had been prepared from magnesium (2.43 g, 100 mmol) and 3-chloro-3-methylpentane (13.6 mL, 100 mmol); trichlorosilane (10.0 mL, 99.1 mmol); and ethylmagnesium chloride THF solution (0.93M, 200 mL, 190 mmol) were employed, whereby the Compound 38a was obtained as a colorless liquid (boiling point; 39 to 42 mmHg, 94 to 97° C. fraction, 8.86 g, 51%).
