実験手順

The compound (1.02 g, 3.19 mmol) obtained in Example 4-1) and the compound (0.81 g, 3.19 mmol) obtained in Example 16-3) were dissolved in 1-butanol (5 mL), and the mixture was stirred at 140° C. for 6 h under a nitrogen atmosphere. The reaction mixture was cooled to room temperature, then the solvent was distilled off, and the obtained residue was purified by silica gel column chromatography (elution solvent: methanol/ethyl acetate=0% to 20%) to obtain the title compound (1.41 g, 85%) in a white solid form.
