Procedure

A suspension of the compound obtained in Example 7-(1) (5.0 g), 4-fluorophenol (2.87 g) and Cs2CO3 (10.4 g) in DMPU (10 ml) was stirred at 200° C. for 1 hour. After cooling to room temperature, the reaction mixture was diluted with methanol/chloroform (1/4) and filtered. The filtrate was concentrated, and the resulting residue was purified by column chromatography (OH-type SiO2, AcOEt/hexane=0% to 30%) to give the titled compound (4.16 g) as a light-pink liquid.
