実験手順

The same procedure as in the steps (14a) to (14e) of Example 14 was repeated using the 3,3-dimethyl-1,5-dioxaspiro[5.5]undecan-9-ol obtained in the step (81a) above to obtain the title compound (275 mg, the total yield of 5 steps: 3.3%) as a white solid. Note that in the same process as in the step (14b), after acetic anhydride was added, 10 equivalents of triethylamine relative to pyridine1-oxide derivative was added to perform the reaction. In the same process as in the step (14c), tetrahydrofuran was used as a solvent instead of ethanol.
