5-Amino-2-methylphenol → 7-Benzyloxy-4-(3-hydroxy-4-methylanilino)-6-methoxyquinoline hydrochloride

Participants

Reaction Steps

A solution of 3-hydroxy-4-methylaniline (68 mg, 0.55 mmol) and 7-benzyloxy-4-chloro-6-methoxyquinoline hydrochloride (168 mg, 0.5 mmol), (prepared as described for the starting material in Example 3), in 2-ethoxyethanol (5 ml) was heated at reflux for 1 hour. The mixture was allowed to cool, the precipitate collected by filtration, washed with 2-ethoxyethanol and then ether and dried under vacuum to give 7-benzyloxy-4-(3-hydroxy-4-methylanilino)-6-methoxyquinoline hydrochloride (130 mg, 61%).
