実験手順

The same procedure as in the steps (4f) to (4j) of Example 4 (a reprecipitation operation was not performed in oxidation step with 3-chloroperbenzoic acid) was repeated using (2,2-diethyl-1,3-dioxolan-4-yl)methanol obtained in the step (65b) above to obtain the title compound (418 mg, total 14.3% yield) as a light yellow solid.
