Versuchsvorschrift
The same procedure as in the steps (14a) to (14e) of Example 14 was repeated using the 1,4-dioxaspiro[4.4]non-6-ylmethanol obtained in the step (80b) above to obtain the title compound (383 mg, the total yield of 5 steps: 14.6%) as a light yellow solid. Note that in the same process as in the step (14c), methanol was used as a solvent instead of ethanol.
