Reaction Conditions:

with trichlorophosphate at 80; for 5 h;

Steps:

1.1
_{4-chloro-2-methylquinoline (compound d) will be 35mL POCl3A mixture with 5 g of 4-hydroxy-2-methylquinoline was heated to 80 ° C for 5 hours.After cooling to room temperature, the reaction mixture was poured into ice water and neutralized with sodium hydroxide and then extracted with dichloromethane.The combined organic layers were dried over anhydrous sodium sulfate and filtered.Using a concentrated organic layer, a pale yellow purified compound was obtained by using silica gel column chromatography and petroleum ether-ethyl acetate (100:1) as eluent.Yield: 5.18 g (93%).}
