To a mixture of 8-(3-amino-2,6-dichlorobenzyloxy)-2-methylquinoline dihydrochloride (4.06 g), 4-dimethylaminopyridine (120 mg), N-methylpyrrolidone (30 ml) and pyridine (10 ml) was added phthalimidoacetyl chloride (3.35 g) at ambient temperature. The mixture was stirred at 50° C. for 1.5 hours and cooled in an ice-water bath. Water (40 ml) was added therein and the mixture was stirred for 30 minutes in an ice water bath. The precipitate was collected by vacuum filtration and washed with water and ethyl acetate to give 8-[2,6-dichloro-3(phthalimidoacetylamino)benzyloxy]-2-methylquinoline (4.45 g) as a yellowish powder.
