Procedure

To a solution of 2-chloro-N-(2-chloro-4-{[2-(trimethylsilyl)ethoxy]methoxy}phenyl)-N-methylacetamide (500 mg) in acetonitrile (8.95 mL) were added tert-butyl 3-{[(2-tert-butoxy-2-oxoethyl)amino]methyl}benzoate (441 mg), potassium carbonate (285 mg), and potassium iodide (22.8 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, 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-{[(2-tert-butoxy-2-oxoethyl){2-[(2-chloro-4-{[2-(trimethylsilyl)ethoxy]methoxy}phenyl)(methyl)amino]-2-oxoethyl}amino]methyl}benzoate (809 mg).
