Participants

Reaction Steps

This compound was prepared according to method F with ethyl 5-benzyl-1,2,4-oxadiazole-3-carboxylate (0.1 g; 0.432 mmol) in methanol (6 mL) and sodium hydroxide in water (2M, 6 mL); and 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.100 g; 0.432 mmol), HART (0.164 g; 0.432 mmol), N,N diisopropylethylamine (0.075 mL; 0.432 mmol), in DMF (6 mL). The crude mixture was purified by flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) to yield 0.072 g (44%) of 5-benzyl-N-(2-(5-chloro-1H-indol-3-yl)ethyl)-1,2,4-oxadiazole-3-carboxamide as a white solid.
