실험 절차
N-(2,2-Dimethoxyethyl)-6-chloro-2-naphthalenesulfonamide was dissolved in DMF (100 ml) and combined with sodium hydride (1.16 g, in oil), cooled to 0° C., treated dropwise with a solution of ethyl bromoacetate (4.843 g) in tetrahydrofuran (15 ml) and then stirred at room temperature for 3 hours. The reaction mixture was concentrated and the residue was dissolved in ethyl acetate, washed with water, aqueous sodium bicarbonate and brine, dried and concentrated to obtain N-(2,2-dimethoxyethyl)-N-(6-chloro-2-naphthalenesulfonyl)glycine ethyl ester as a colorless oil.
