Reaction Steps

A solution of 4-chloro-2-ethyl-8-methoxyquinoline (4.0 g) in 48% hydrobromic acid (80 ml) was refluxed for 2 days. The mixture was adjusted to pH 12 with 28% ammonia solution. The precipitate was collected by vacuum filtration, and was washed with water and hexane to give 4-chloro-2-ethyl-8-hydroxyquinoline (3.13 g) as crystals.
