Procedure

Subsequently, in 70 ml of DMF, 3.5 g of the compound (F), 2.4 g of p-chlorobenzyl alcohol and 12 g of potassium carbonate were stirred at 120° C. for 5 hours. After filtration, DMF was removed under reduced pressure, and purification was carried out by column chromatography to yield 2.5 g of the target anthraquinone dye No. 8.
