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-methyl-1,3-dioxolan-2-yl)ethanol obtained in the step (69b) to obtain the title compound (410 mg, total 14.4% yield) as a light yellow solid.
