This compound was prepared according to method F with ethyl 5-phenyl-1,2,4-oxadiazole-3-carboxylate (0.075 g; 0.346 mmol) in THF (1 mL) and sodium hydroxide in water (2M, 1 mL); 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.080 g; 0.346 mmol), HATU (0.131 g; 0.346 mmol), N,N diisopropylethylamine (0.149 mL; 0.865 mmol), in DMF (4 mL). The crude mixture was purified by flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) and preparative HPLC method 2 to yield 0.034 g (24%) of N-(2-(5-chloro-1H-indol-3-yl)ethyl)-5-phenyl-1,2,4-oxadiazole-3-carboxamide as a white solid.
