To a mixed solution of the crude product (402 mg) of (6-(3-(4-ethylpiperazin-1-yl)azetidin-1-yl)-5-fluoropyridin-2-yl)methanol described in Production Example 7-1 and dichloromethane (10.0 mL) was added Dess-Martin periodinane (787 mg, 1.86 mmol) at room temperature. The resultant mixture was stirred at room temperature for 2 hours. A saturated aqueous sodium thiosulfate solution and a saturated aqueous sodium hydrogen carbonate solution were added to the reaction mixture, and the resultant solution was extracted with dichloromethane. An organic layer was dried over anhydrous magnesium sulfate and then filtrated. The solvent was evaporated under a reduced pressure to give a crude product (362 mg) of the title compound. The product was used in the subsequent reaction without further purification.
