Reaction Steps
To a solution of tert-butyl 3-(chloromethyl)benzoate (500 mg) in N,N-dimethylformamide (10.0 mL) were added tert-butyl 4-aminobenzoate (426 mg), potassium carbonate (610 mg), and potassium iodide (36.6 mg), followed by stirring at 60° C. overnight. To the reaction suspension was added water, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution, then dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain tert-butyl 3-({[4-(tert-butoxycarbonyl)phenyl]amino}methyl)benzoate (671 mg).
