65% With bromine; In acetonitrile; EXAMPLE 4 4-[1-[(4-Fluorophenyl)oxy]ethyl]-5,7-dichloroquinoline STR10 Bromine (15 ml, 0.30 mol) was dissolved in acetonitrile (200 ml) and added dropwise to a suspension of <strong>[171850-29-6]4-hydroxy-5,7-dichloroquinoline</strong> (60 g, 0.28 mol) (Swiss Pat. CH 93-3640 931207) and triphenylphosphite (78 ml, 0.30 mol) in acetonitrile (1 L) over three hours. The reaction was left to stir for 24 hours at which point it was filtered to collect the precipitate. The solid was suspended between water (1 L) and dichloromethane (500 ml) and neutralized with sodium bicarbonate. Extractions were performed periodically as the aqueous layer neared neutral and finally at pH 10 to give a total of 5*500 ml aliquots. The organics were combined, dried (magnesium sulfate), filtered through a plug of silica gel, and concentrated under vacuum to a total volume of 1 L, then heated until solid dissolved and left to crystallize 12 hours. Filtration gave analytically pure product (46 g, 65%) while concentration of the mother liquor gave spectroscopically clean product (14 g, 20%, mp 131 C.).

99% The reaction product was analyzed by liquid chromatography whereupon 5,7-dichloro-3-carboxy-4-hydroxyquinoline disappeared and 5,7-dichloro-4-hydroxyquinoline was produced in 99% yield. The reaction product was cooled to 100 C., crystallized by adding 258 g of water gradually thereto, cooled to 30 C. and filtered.
99% The crystals were poured into 600 g of water, heated at 40-45 C., neutralized with aqueous 48% sodium hydroxide with stirring to pH 3-4, filtered at 30 C., washed with water, further washed with 80 ml of isopropanol and dried to give 84.0 g of 5,7-dichloro-4-hydroxyquinoline (purity: 99%; yield: 98%).
