Reaction Steps

A solution of 0.53 g (1.6 mmol) {methyl-[4-(4-oxo-piperidin-1-yl)-benzenesulfonyl]-amino}-acetic acid in 8 mL anhydrous tetrahydrofuran was treated with 0.32 g (2.0 mmol) 1,1′-carbonyl-diimidazole. After stirring for 45 minutes, 1 mL of ethanol was added. The resulting mixture was then permitted to stir overnight. The solvent was removed in vacuo and the residue was dissolved in ethyl acetate. The organics were washed twice with saturated sodium bicarbonate, twice with water, dried over sodium sulfate and concentrated in vacuo. After drying via high vacuum overnight, 0.76 g of the title compound was isolated as a red solid; 1H NMR (CDCl3) δ 1.23-1.29 (m, 3H), 2.59 (t, J=6.15 Hz, 4H), 2.87 (s, 1H), 3.76 (t, J=6.09 Hz, 4H), 3.96 (s, 2H), 4.11-4.18 (m, 2H), 6.89-6.96 (m, 2H), 7.67-7.75 (m, 2H); MS (ES) m/z 355.3 (MH+); HRMS for C16H22N2O5S: 355.1332
