Reaction Steps

A solution of 4,7-dichloroquinoline (198 mg, 1 mmol) and 2-fluoro-5-hydroxy-4-methylaniline (1 69 mg, 1.2 mmol), (prepared as described for the starting material in Example 1), in 2-pentanol (5 ml) containing 5M hydrochloric acid in isopropanol (0.5 ml) was heated at reflux for 2 hours. The volatiles were removed by evaporation and the residue was triturated with ether. The solid was collected by filtration, washed with isopropanol, followed by ether and dried under vacuum to give 7-chloro-4-(2-fluoro-5-hydroxy-4-methylanilino)quinoline hydrochloride (300 mg, 88%).
