Reaction Steps

To a solution of di-tert-butyl 5-(bromomethyl)isophthalate (1.00 g) in tetrahydrofuran (10.0 mL) were added a 70% aqueous ethylamine solution (2.21 mL), followed by stirring at room temperature overnight. To the reaction mixture were added water and ethyl acetate, and the organic layer was extracted. The organic layer was washed with water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate, and subsequently chloroform-methanol) to obtain di-tert-butyl 5-[ethylamino(methyl)]isophthalate (558 mg).
