To a solution of N-benzyloxy-[(4-methoxybenzenesulfonyl)(2-morpholin-4-yl-2-oxoethyl)amino]acetamide (0.33 grams, 0.69 mmol) in methanol (35 mL) was added 5% palladium on activated carbon (85 mg). The mixture was agitated under 2 atmospheres hydrogen in a Parr shaker for 1.5 hours. The catalyst was removed by filtration through nylon (pore size 0.45 μm) and the solvent was evaporated. The residue was chromatographed on silica gel eluting with 5% methanol in methylene chloride to afford N-methoxy-[(4-methoxybenzenesulfonyl)(2-morpholin-4-yl-2-oxoethyl)amino]acetamide as a white solid, 65 mg (24%); 1H NMR (CD3OD): δ 7.82 (d, J=9.0 Hz, 2H), 7.08 (d, J=9.0 Hz, 2H), 4.24 (s, 2H), 3.88 (s, 3H), 3.84 (s, 2H), 3.68-3.64 (m, 4H), 3.581-3.50 (m, 4H); MS (thermospray): m/z 388 (M+1), 387 (M); HRMS calculated for C16H22N3O7S (M+H): 388.1178, Found 338.1180.
