実験手順

A mixture of ethyl 2-methyl-1H-indole-3-carboxylate (400 mg, 1.97 mmol) and sodium hydride (47 mg, 2.0 mmol) in N,N-dimethylformamide (5.0 mL) was stirred at room temperature for 0.5 hours, and then (1-bromoethyl)benzene (361 mg, 2.0 mmol) was added. The mixture was stirred at room temperature for 3 hours. The reaction mixture was poured into ice-cold water and extracted with ethyl acetate. Organic layers were combined and concentrated to give a residue. The residue was purified by chromatography (petroleum ether/ethyl acetate=5:1) to give ethyl 2-methyl-1-(1-phenylethyl)-1H-indole-3-carboxylate (340 mg, 56%). LRMS (M+H+) m/z: calcd 307.16. found 307.
