Reaction Steps
The same procedure as in the steps (5d) to (5h) of Example 5 (a reprecipitation operation was not performed in oxidation step with 3-chloroperbenzoic acid) was repeated using 2-(9-methyl-1,5,8,10-tetraoxaspiro[5.5]undec-9-yl)ethanol obtained in the step (76d) above to obtain the title compound (228 mg, total 11.4% yield) as a white solid.
