Reaction Steps

To a mixture of 8-[2,6-dimethoxy-3-nitrobenzyloxy]-2-methylquinoline (2.28 g), ferrric chloride (68 mg), carbon (68 mg) and methanol (34 ml) was added hydrazine monohydrate (1.25 ml) at 60° C., and the mixture was refluxed for 4 hours. Ferric chloride (68 mg), carbon (68 mg), hydrazine monohydrate (1.25 ml) and methanol (10 ml) was further added, and the mixture was refluxed overnight. Insoluble materials were filtered off, and the filtrate was concentrated. The residue was dissolved in chloroform, and the solution was washed with saturated sodium bicarbonate solution, water and brine, dried over magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography (chloroform-methanol) and crystallized with methanol to give 8-[3-amino-2,6-dimethoxybenzyloxy]-2-methylquinoline (1.33 g) as pale brown crystals.
