To a mixture of 8-[2,6-dichloro-3-(phthalimidoacetylamino)benzyloxy]-2-methylquinoline (4.44 g) and N,N-dimethylformamide (44 ml) was added sodium hydride (60% in oil, 375 mg) in an ice-water bath. After stirring for 30 minutes in an ice-water bath, methyl iodide (0.6 ml) was added thereto and the mixture was stirred at ambient temperature for 1 hour. To this mixture was added, water (88 ml) in an ice-water bath and the mixture was stirred at the same temperature for 1.5 hours. The precipitate was collected by vacuum filtration and washed with water and methanol to give 8-[2,6-dichloro-3-[N-(phthalimidoacetyl)-N-methylamino]benzyloxy]-2-methylquinoline (3.99 g) as a yellow powder.
