Reaction Steps

A mixture of the indole (0.040 g, 0.14 mmol) from step A, Cs2CO3 (0.054 g, 0.16 mmol), 5-[3,5-bis(trifluoromethyl)phenyl]-3-(chloromethyl)-1,2,4-oxadiazole (0.091 g, 0.27 mmol) and CH3CN (4 mL) was stirred at 50° C. for 24 h. The mixture was diluted with EtOAc (25 mL) and washed with water (15 mL) and brine (15 mL). Drying (MgSO4), filtration, and concentration was followed by purification (SiO2, 0-30% EtOAc in hexanes) to afford the title compound (0.015 g, 19%) as an off-white solid: 1H NMR (400 MHz, CDCl3) δ 8.48 (s, 2H), 8.10 (s, 1H), 7.80 (d, J=8.6 Hz, 1H), 7.65 (d, J=8.6 Hz, 1H), 6.96 (s, 1H), 5.58 (s, 2H), 3.94 (q, 2H); MS m/z 585 (M−H).
