実験手順

The compound (2.07 g, 6.54 mmol) obtained in Example 3-1) and the compound (1.38 g, 6.54 mmol) obtained in Example 1-1) were dissolved in 1-butanol (10 mL), and the mixture was stirred at 140° C. for 5 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: ethyl acetate/hexane=30% to 80%) to obtain the title compound (1.27 g, 42%) in a white solid form.
