实验步骤: To a mixture of 8-[3-(N-glycyl-N-methylamino)-2,6-dichlorobenzyloxy]-2-methylquinoline (150 ml), triethylamine (0.077 ml) and dichloromethane (1.5 ml) was added bromoacetyl chloride (0.034 ml) in a dry ice-acetone bath. After 30 minutes, to the mixture was added N-methyl-N-cycloheptylamine (236 mg). The mixture was stirred for 3 hours at ambient temperature. The reaction mixture was washed with aqueous sodium bicarbonate solution, water and brine. The organic layer was dried over magnesium sulfate and evaporated in vacuo. The residue was purified by a silica gel column chromatography (dichloromethane-methanol) to yield 8-[3-[N-[(N-cycloheptyl-N-methylglycyl)glycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methylquinoline (151 mg) as amorphous. The reaction mixture was washed with aqueous sodium bicarbonate solution, water and brine The organic layer was dried over magnesium sulfate evaporated in vacuo The residue was purified by a silica gel column chromatography (dichloromethane-methanol)

实验步骤: In 1,2-dichloroethane (50 ml) were suspended cycloheptanone (2 g), methylamine hydrochloride (3 g) and triethylamine (6.2 ml), and to the suspension was added sodium triacetoxy boron hydride (5.3 g) under ice-cooling. Under nitrogen atmosphere, the mixture was stirred at room temperature over night. The solvent was evaporated, and the residue was neutralized with sodium hydroxide. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated to give N-methylcycloheptylamine (1.8 g) as colorless oil. cooling The solvent was evaporated The mixture was extracted with ethyl acetate The organic layer was washed with saturated sodium chloride solution dried with anhydrous magnesium sulfate Under reduced pressure, the solvent was evaporated
