Reaction Steps

To a solution of methyl 2-({[3-(2-chloro-4-hydroxyphenyl)propanoyl]amino}methyl)benzoate (380 mg) in N,N-dimethylformamide (4.00 mL) were added chloro tert-butyl dimethylsilane (215 mg) and imidazole (114 mg), followed by stirring at room temperature for 4 hours. To the reaction mixture were added water and 1 M hydrochloric acid, followed by extraction with ethyl acetate. The organic layer was washed with 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 methyl 2-({[3-(4-{[tert-butyl(dimethyl)silyl]oxy}-2-chlorophenyl)propanoyl]amino}methyl)benzoate (500 mg).
