Procedure

To a mixture of 8-(2,6-dichloro-3-nitrobenzyloxy)-2-methylquinoline (1.0 g), concentrated hydrochloric acid (5.2 ml) and methanol (5.2 ml)) was added iron powder (666 mg). The mixture was heated under reflux for 2 hours and stirred in an ice-water bath for 1 hour. The precipitate was collected by vacuum filtration and washed with 1 N hydrochloric acid and water to give 8-(3-amino-2,6-dichlorobenzyloxy)-2-methylquinoline dihydrochloride (635 mg) as a brownish powder.
