Reaction Steps

To a suspension of 5-(4-bromo-2-formyl-N-propylanilino)pentanoic acid (8.00 g) and potassium carbonate (3.88 g) in DMF (25 ml) was added dropwise a solution of iodomethane (4.66 g) in DMF (5 ml) under a nitrogen atmosphere. The mixture was stirred overnight under a nitrogen atmosphere. Then, water was added and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated saline and dried over magnesium sulfate. The solvent was distilled off under reduced pressure to obtain brown oil of methyl 5-(4-bromo-2-formyl-N-propylanilino)pentanoate (7.89 g).
