To a solution of 0.25 g (0.620 mmol) of methyl [{[4-(2-butynyloxy)phenyl]sulfonyl}(methyl)amino](4-hydroxyphenyl)acetate in 10 mL of acetone was added 0.342 g of potassium carbonate, 0.231 g (1.241 mmol) of 4-(2-chloroethyl)morpholine hydrochloride and 1 equivalent of sodium iodide. The reaction was heated to reflux for 5 h, diluted with water and extracted with chloroform. The organics were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was chromatographed on silica gel eluting with chloroform/methanol (9:1) to provide 0.156 g of methyl 2-[{[4-(2-butynyloxy)phenyl]sulfonyl}(methyl)amino]-2-{4-[2-(4-morpholinyl)ethoxy]phenyl}acetate.
