실험 절차
A mixture of 1-(3-thienyl)-2H-indole-2,3-dione (25 mg, 0.11 mmol) (prepared as described below) and 3-trifluoromethylaniline (14 uL, 0.11 mmol) was heated neat at 140° C. for 2 h. The crude material was purified by preparative TLC using a mixture of 3:7 ethyl acetate and hexane as the eluent, giving the desired product as a yellow solid (7.3 mg, 0.02 mmol, 22%). 1H NMR (400 MHz) δ 7.62–7.19 (m, 9H), 6.94 (d, J=8.0, 1H), 6.76 (t, J=7.6, 1H); ESI-MS m/z found 373 (MH+).
