Using the same reaction conditions as described in Example 20-step a except that methyl 4-chloro-3-oxobutyrate replaced methyl 3-chloro-3-oxopropionate, aniline (2.33 g, 25 mmol) was converted to the succinamide compound (5.18 g, 100%) after purification by chromatography over silica gel. 1H NMR (400 MHz, CDCl3) δ: 7.70 (s, 1H), 7.50 (d, 2H), 7.30 (t, 2H), 7.09 (m, 1H), 3.70 (s, 3H), 2.73–2.65 (m, 4H).
