Procedure

150 ml in dichloromethane of 4.46 g of 7-(1-ethylpropoxy)-5-hydroxy-2-(4-hydroxyphenylthio)-6-methoxychromone obtained in Example 33, 7.21 g of 4-(4-methylpiperazinomethyl)benzoxychloride dihydrochloride, 7.78 ml of triethylamine was stirred over 3 hours at room temperature. The solution thus reacted was concentrated, and an aqueous solution of sodium bicarbonate was added to the resulting residues, and the product was extracted with ethyl acetate. The organic layer was concentrated, and the residues thus obtained were purified by flash column chromatography (chloroform:methanol=30:1), whereby 2.31 g of 7-(1-ethylpropoxy)-5-hydroxy-2-{4-[4-(4-methylpiperazinomethyl)benzoyloxy]phenylthio}-6-methoxychromone was obtained.
