The obtained solution was agitated at -70 C. to 40 C. for 1 hour. The reaction flux was frozen to -70 C. and slowly added with 29.3 ml (144 mmol) of isopropyl tetramethyl dioxaborolane in a dropwise fashion. The obtained solution was agitated at -70 C. for 1 hour, and heated to room temperature and agitated for 6 hours. The obtained reaction solution was added with 200 ml of water and agitated for 20 minutes.After the reaction solution was separated into two liquid layers, an organic layer thereof was dried with anhydrous sodium sulfate.
