Activated carbon (2.2 g) was added to this solution and stirred for 10 minutes. This suspension was hot filtered and washed with 35.2 g of acetone. 220.0 g of acetone was then added, and the reaction solution was heated to an external temperature of 52°C and stirred. Next, 44.0 g of water was added to the reaction solution. Separately, 8.73 g of succinic acid was dissolved in a mixed solution of 156.1 g of acetone and 19.8 g of water. This succinic acid solution was added dropwise to the reaction solution over approximately 10 minutes. The dropping funnel was washed with a mixed solution of 17.4 g of acetone and 2.2 g of water and then added dropwise to the reaction solution. The reaction solution was stirred at an internal temperature of 50°C for 1 hour and cooled to 15°C over 30 minutes. The reaction solution was stirred at an external temperature of 10°C for 2 hours, and the crystals were collected by filtration. The crystals were washed twice with 52.8 g of acetone. The obtained wet crystals were dried under reduced pressure at 50°C for 37 hours and then returned to room temperature under reduced pressure over 3 hours. The crystals were stored under air for 24 hours to obtain crystals (27.75 g) of the title compound.
