Procedure

To a mixture of 4-hydroxy-benzoic acid [2-(4-hydroxy-phenyl)-1-methoxycarbonyl-ethyl carbamoyl]-methoxycarbonylmethyl ester 17 (10.7 grams, 24.82 mmol) anhydrous potassium carbonate (17.5 grams, 126.62 mmol), sodium iodide (3 grams, 20.01 mmol), and disodium phosphate (3 grams, 21.13 mmol) in anhydrous acetone (100 mL) is added methyl chloro acetate (7 grams, 64.5 mmol). The mixture is refluxed for 10 hours. Acetone is distilled off, and water (100 mL) is added. Crude 18 is filtered, dried, and can be purified in appropriate solvent.
