실험 절차

A mixture of 2-propyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile (0.040 g, 0.16 mmol), 5-[3,5-bis(trifluoromethyl)phenyl]-3-(chloromethyl)-1,2,4-oxadiazole (0.058 g, 0.17 mmol), Cs2CO3 (0.057 g, 0.17 mmol) and CH3CN (4 mL) was stirred at 75° C. for 1.5 h. The mixture was diluted with EtOAc (25 mL), washed with water (15 mL), and brine (15 mL). The organic portion was dried (MgSO4), filtered, and concentrated. The concentrated material was treated with 10% Et2O in hexanes (10 mL) and stirred for 2 h. The resulting solid was filtered, rinsed with hexanes, and dried to afford the title compound (0.070 g, 81%) as a light tan solid: 1H NMR (400 MHz, DMSO-d6) δ 8.53 (s, 2H), 8.50 (s, 1H), 8.03 (d, J=8.6 Hz, 1H), 7.75 (d, J=8.6 Hz, 1H), 6.59 (s, 1H), 5.90 (s, 2H), 2.90 (t, J=7.5 Hz, 2H), 1.79-1.70 (m, 2H), 0.98 (t, J=7.4 Hz, 3H); MS m/z 547 (M+H).
