반응 단계

To a solution of indole (2.88 g, 25 mmol) and methyl trans-cinnamate (3.98 g, 25 mmol) in anhydrous DMF (50 mL) was added a suspension of 60% NaH (0.29 g, 7 mmol) at room temperature. The reaction mixture was allowed to stir for 6 hours at room temperature. The reaction mixture was poured into water (300 mL) and product was extracted with EtOAc (2×200 mL). The combined organic extracts were washed with water (5×200 ml), dried over Na2SO4 and evaporated under vacuum. Purification by chromatography (SiO2, benzene-hexane, 1:9) afforded 1.51 g (22% yield) of 3-indol-1-yl-3-phenyl-propionic acid methyl ester as a white powder: MS 280 (M+H)+.
