After stirring the reaction solution at room temperature for 14 hours, water (60 mL) was added. The reaction solution was stirred at room temperature for 30 minutes, and then the precipitate was collected by filtration. The obtained yellow solid was washed with water and hexane to give the title compound (1.97 g).
