Procedure

To a suspension of sodium hydride (0.84 g, 35.0 mmol) in dimethylformamide (120.0 mL), is added ethyl 2-[[4-methoxybenzenesulfonyl]amino]acetate (3.19 g, 11.67 mmol) and 2-(chloromethyl)quinoline (2.62 g, 12.26 mmol), and the reaction is stirred for three days at room temperature. Then, additional NaH (0.46 g, 11.67 mmol) is added, and the reaction is heated to 50° C. for 5 hours. The reaction is cooled to 0° C., quenched with water, and extracted well with ether. The combined organic layers are washed with brine, dried (Na2SO4), and the solvent is removed to give ethyl 2-[[4-methoxybenzenesulfonyl]-(2-quinolinylmethyl)amino]acetate.
