To a solution of [(4-methoxybenzenesulfonyl)(2-morpholin-4-yl-2-oxoethyl)amino]acetic acid (0.33 grams, 0.89 mmol) in methylene chloride (10 mL) were added sequentially triethylamine (0.43 mL, 3.1 mmol), O-benzylhydroxylamine hydrochloride (0.15 grams, 0.94 mmol) and (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (0.43 grams, 0.97 mmol). The mixture wsa stirred at room temperature overnight and then diluted with ethyl acetate. The solution wsa washed sequentially with 0.5 N hydrochloric acid solution, water and brine, dried over magnesium sulfate and concentrated under vacuum. The residue was chromatorgraphed on silica gel using ethyl acetate to afford N-benzyloxy-[(4-methoxybenzenesulfonyl)(2-morpholin-4-yl-2-oxoethyl)amino]acetamide as a white solid, 0.33 grams (78%).
