実験手順

The compound (2.09 g, 6.54 mmol) obtained in Example 4-1) 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 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: ethyl acetate/hexane=30% to 90%) to obtain the title compound (2.63 g, 87%) in a white solid form.
