Procedure
The same procedure as in the steps (9h) to (9j) of Example 9 was repeated using the (4-(5,9-dioxaspiro[3.5]non-7-yloxy)pyridin-2-yl)methanol obtained in the step (83b) above to obtain the title compound (100 mg, the total yield of 3 steps: 50%) as a white solid. Note that, in the same process as in the step (9h), 2-mercaptobenzimidazole was added to the reaction mixture and stirred at room temperature for 25 hours, and thereafter, 3 equivalents of potassium hydroxide relative to the alcohol was added thereto. The mixture was allowed to react at room temperature for 6 hours.
