To a solution of 1-benzyl-2-isopropyl-5-methoxy-1H-indole-3-carbohydrazide (Compound 35, 25 mg, 0.074 mmol) in EtOH (2.0 ml) was added ethyl benzimidate hydrochloride (Fluka, 21 mg, 0.11 mmol). The mixture was stirred at 80° C. for 4 h and was concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with 0-30% EtOAc-hexanes to yield 2-(1-benzyl-2-isopropyl-5-methoxy-1H-indol-3-yl)-5-phenyl-1,3,4-oxadiazole (Compound 36) as a white solid.
