Methanol → HCID 22646514, compound

Participants

Reaction Steps

A mixture of 4-chloro-6-cyano-7-methoxyquinoline hydrochloride (500 mg, 2 mmol), (prepared by an analogous procedure to that described for the starting material in Example 1 but using methanol instead of 2-methoxyethanol), and 2-fluoro-5-hydroxy-4-methylaniline (141 mg, 1 mmol), (prepared as described for the starting material in Example 1), in isopropanol (10 ml) was heated at reflux for 4 hours. The mixture was allowed to cool, the solid product was collected by filtration, washed with acetone and dried to give 6-cyano-4-(2-fluoro-5-hydroxy-4-methylanilino)-7-methoxyquinoline hydrochloride (176 mg, 54%) as a light brown solid.
