Reaction Steps

To a solution of 7-((4-bromo-2-formylphenyl)(4-methoxybenzyl)amino)heptanoic acid (41.0 g) and potassium carbonate (15.2 g) in DMF (400 ml) was added dropwise a DMF (100 ml) solution of iodomethane (18.2 g) under nitrogen atmosphere at 0° C. After returning to room temperature, the reaction mixture was stirred for 2 hours, water was added thereto and the mixture was extracted with ethyl acetate. The organic layer was washed with water five times and with saturated brine once, and dried with magnesium sulfate. The solvent was distilled off under reduced pressure to give methyl 7-((4-bromo-2-formylphenyl)(4-methoxybenzyl)amino)heptanoate (40.8 g) as a brown oily material.
