Procedure

A suspension of N-(4′-Chloro-5′-ethyl-2′-nitrophenyl)glycine sodium salt (0.082 g, 0.31 mmol) and tin (II) chloride dihydrate (0.215 g, 0.953 mmol) in ethanol (1.0 mL) was refluxed for 45 min. It was then cooled to room temperature and the precipitated solid was filtered, washed with ethanol (1.0 mL), and dried under vacuum to yield 0.048 g (72%) pure (1H NMR) title compound as a light yellow powder; 1H NMR (DMSO-d6) δ 1.05 (t, 3H, J=7.2 Hz), 2.52 (d, 2, J=7.2), 3.67 (s, 2H), 6.04 (s, 1H), 6.54 (s, 1H), 6.67 (s, 1H), 10.25 (s, 1H).
