실험 절차
Methanesulfonic acid (1.42 mL) was added to a suspension of the compound (7.2 g) obtained in Example 1 in water (50 mL), was heated with stirring until the compound was dissolved, followed by cooling to room temperature with stirring. The crystals were collected by filtration and were recrystallized from water (50 mL). The resulting crystals were collected by filtration, washed with acetone, and dried under reduced pressure to yield the titled compound (7.6 g) as crystals.
