Reaction Steps

Freshly prepared hydroxylamine reagent (20 mL; 20 mmol) was added to ethyl 3-[(phenyl)-(4-methoxy-benzenesulfonyl)-amino]-propionate (3.30 g; 9.1 mmol) and the resulting mixture stirred for 18 h at room temperature. The mixture was poured into 1 N HCl (100 mL) and extracted with CH2Cl2 (2×100 mL). The combined extracts were washed with saturated aqueous NaCl (1×100 mL), dried over MgSO4, and evaporated under reduced pressure to give a crude gum. Trituration with diethyl ether afforded 2.14 g (68%) of the title compound as an off-white solid. 300 MHz 1H-NMR (DMSO-d6): δ 2.12 (t, 2H), 3.74 (t, 2H), 3.86 (s, 3H), 7.03 (d, 2H), 7.08 (d, 2H), 7.32 (m, 3H), 7.47 (d, 2H), 8.74 (s, 1H), 10.35 (s, 1H).
