A solution of sodium (0.412 g) in absolute ethanol ((200 mL) was treated with 2-(4-acetylaminophenyl)-indan-1,3-dione (5 g, Reference Example 14) then with sodium iodide (2.69 g) and chloroacetic acid ethyl ester (3.6 mL). The mixture was heated at 100° C. for 20 minutes then poured into water (500 mL) and then extracted with ethyl acetate (500 mL).
