Procedure
N-{3-[2-(4-Cyanophenyl)ethoxy]phenyl}benzenesulfonamide (0.179 g; 0.47 mmol; from Example 1(iv) above), K2CO3 (0.082 g; 0.59 mmol) and ethyl bromoacetate (63 μL; 0.57 mmol) were stirred in DMF (10 mL) for 1 hour at room temperature, then 1 hour at 60° C. The mixture was filtered and the solvent removed in vacuo. The residue was dissolved in EtOAc and washed with water. The aqueous phase was extracted with EtOAc. The combined organic portions were dried (Na2SO4) and the solvent evaporated to afford the sub-title compound in a quantitative yield.
