Procedure

The compound (3.0 g, 6.0 mmol) obtained in Example 3 was dissolved in ethanol (75 mL), and a solution of fumaric acid (693 mg, 6.0 mmol) in ethanol (25 mL) and further methanol (100 mL) were added thereto. The dissolution thereof was confirmed, and the solvent was then distilled off under reduced pressure to obtain a concentrated residue. To this concentrated residue, acetone (110 mL) was added, and the mixture was stirred at room temperature for 2.5 hours. The resulting precipitate was collected by filtration and dried under reduced pressure (40° C., 1 mmHg, 18 hours) to obtain the title compound (3.26 g, 88%) as a colorless crystalline solid.
