Participants

Reaction Steps

0.029 mL of 2-phenoxyacetyl chloride was added to 2.5 mL of methylene chloride solution containing 40 mg of tert-butyl 2-amino-4-phenoxybenzoate and 0.039 mL of triethylamine at room temperature and stirred at the same temperature for 2 hours. 0.25 g of aminomethylated polystyrene was added to the reaction mixture and after stirred at the same temperature overnight, 5 mL of 10% citric acid aqueous solution was added. The organic layer was separated and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [Flash Tube 2008 manufactured by Trikonex Company, eluent; hexane:ethyl acetate: acetic acid=20:5:1] to obtain tert-butyl 4-phenoxy-2-(2-phenoxyacetamido)benzoate.
