Bis(triphenylphosphine)palladium (II) dichloride (0.052 g, 0.073 mmol) was added thereto, and the resultant was stirred at 65° C. for 3 hours. Water was added to this reaction solution, which was subsequently extracted with toluene. The resulting organic layer was dried over anhydrous magnesium sulfate and then partially purified with activated earth. The thus obtained partial purification product was further purified by column chromatography (developer: hexane/methylene chloride=75/25), whereby the compound 25 (4.8g, yield: 76.0%) was obtained.
[Synthesis of Compound 27]
Subsequently, the compound 25 (4.6 g, 5.13 mmol), the compound 26 (2.2 g, 6.67 mmol), potassium carbonate (2.1 g, 15.4 mmol), toluene (24 ml), ethanol (8 ml), and water (8 ml) were added to a flask, and this system was sufficiently purged with nitrogen and heated to 60° C. Tetrakis(triphenylphosphine)palladium (0) (0.18 g, 0.154 mmol) was added thereto, and the resultant was stirred at 85° C. for 3.5 hours. Water was added to this reaction solution, which was subsequently extracted with toluene. The resulting organic layer was dried over anhydrous magnesium sulfate and then partially purified with activated earth. The thus obtained partial purification product was further purified by column chromatography (developer: hexane/methylene chloride=60/40), whereby the compound 27 (3.9 g, yield: 74.9%) was obtained.
