Procedure

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-methyl-1,3-dioxolan-2-yl)methanol obtained in the step (67b) above to obtain the title compound (263 mg, total 12.9% yield) as a light yellow solid.
