Reaction Steps

Freshly prepared hydroxylamine reagent (8 mL; 8 mmol) was added to ethyl 3-[(diphenylmethyl)-(4-methoxybenzene-sulfonyl)-amino]-propionate (563 mg; 1.24 mmol) and the resulting mixture stirred overnight at room temperature. The mixture was poured into 1 N HCl (100 mL) and extracted with CH2Cl2 (2×50 mL). The combined extracts were washed with saturated aqueous NaCl (100 mL), dried over MgSO4, and evaporated under reduced pressure to give crude product. Trituration with diethyl ether afforded 262 mg (48%) of the title compound as a white solid. 300 MHz 1H-NMR (DMSO-d6): δ 1.81 (m, 2H), 3.40(m, 2H), 3.84 (s, 3H), 6.31 (s, 1H), 7.02 (m, 6H), 7.28 (m, 6H), 7.71 (d, 2H), 8.59 (s, 1H), 10.23 (s, 1H).
