The organic layer was washed with water and brine, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by preparative thin-layer chromatography (chloroform:methanol=20:1, V/V) to give 8-[2,6-dichloro-3-methylamino]benzyloxy]-2-methylquinoline (30 mg) as colorless amorphous.
