実験手順

To a stirring solution of 2-ethyl-aniline (74 μL, 0.6 mmol) and DIEA (110 μL, 0.6 mmol) in DMF (1 mL) was added a solution of (1H-indol-3-yl)-oxo-acetyl chloride (62 mg, 0.3 mmol) in DMF (1 mL). The reaction was stirred at room temperature for 2 hours, then filtered and purified by HPLC (10-99% CH3CN/H2O) to yield the product N-(2-ethyl-phenyl)-2-(1H-indol-3-yl)-2-oxo-acetamide (34 mg, 39%). HPLC ret. time 3.50 min, 10-99% CH3CN, 5 min run; 1H NMR (400 MHz, DMSO-d6) δ 12.33 (s, 1H), 10.14 (s, 1H), 8.79 (d, J=3.2 Hz, 1H), 8.30 (m, 1H), 7.57 (m, 2H), 7.33-7.21 (m, 5H), 2.67 (q, J=7.6 Hz, 2H), 1.17 (t, J=7.6 Hz, 3H); ESI-MS m/z 293.1 (MH+).
