実験手順
A mixture of compound 5 (0.50 mmol) and indolin-2-one (0.50 mmol) was added with EtOH (5.0 mL) and piperidine (0.1 mL). The reaction was heated at reflux for 12 h. The resultant precipitate was filtered and washed with EtOH to provide the diresed product. 1H NMR (CDCl3) δ 7.93 (s, 1 H), 7.61 (s, 1 H), 7.59 (d, 1 H, ArH), 7.19 (dd, 1 H), 7.09 (dd, 1 H), 6.89 (d, 1 H), 4.07 (q, 2 H), 3.27 (t, 2 H), 2.91 (t, 2 H), 2.74 (t, 2 H), 2.52 (t, 2 H), 2.14-2.19 (m, 2 H), 1.18 (t, 3 H).
