Reaction Steps

To a stirred solution oxazole (0.1 g, 1.45 mmol) in anhydrous THF (3 mL), n-BuLi (1.6 mL, 1.6 mmol) was added at −78° C. and stirred for 30 minutes. The reaction mixture was brought to 0° C., ZnCl2.Et2O (4.35 mL, 4.35 mmol) was added and stirred for 1 h. 5-iodo-1H-indole (0.352 g, 1.45 mmol) and (Ph3P)PdCl2 (0.050 g, 0.072 mmol) were added and stirred at 80° C. for 1 h. The reaction mixture was quenched with water and the mixture was extracted with ethyl acetate. The organic layer was concentrated in vacuo and the residue was purified by flash column chromatography to give 2-(1H-indol-5-yl)oxazole (0.060 g, 22%); MS: 185.0 (M+1).
