The organic layer was dried over magnesium sulfate, concentrated under a reduced pressure, and crystallized at 5° C. in 305 ml of isopropanol and 122 ml of water to obtain the white title compound (85.6 g). Then, the filtrate was additionally concentrated under a reduced pressure, and crystallized at 5° C. in 30 ml of isopropanol to obtain 12.3 g of the title compound (total: 97.9 g, total yield: 96%).
