実験手順: To a solution of the allyl 2,3-dimethyl-1H-indole-5-carboxylate (500 mg, 2.2 mmol) in anhydrous DMF (20 mL) was added the methyl 2-(4-(bromomethyl)phenoxy)acetate (565 mg, 2.2 mmol) followed by NaH (131 mg, 3.3 mmol). The resulting solution was allowed to stir overnight under argon atmosphere. The remaining NaH was hydrolyzed by the careful addition of a 0.5 N HCl solution. The mixture was diluted with ethyl acetate, washed with a 0.5 N HCl solution and brine, dried on MgSO4, and concentrated. The crude residue was purified by chromatography on silica gel (Hexane/Ethyl acetate 5/5) to afford yellow oil (536 mg, 61%). ESI-MS (m/z): 408 [M+H]+ washed with a 0.5 N HCl solution and brine dried on MgSO4 concentrated The crude residue was purified by chromatography on silica gel (Hexane/Ethyl acetate 5/5)

実験手順: To a solution of the methyl 2-(p-tolyloxy)acetate (3.10 g, 17.2 mmol) in carbon tetrachloride (60 mL) was added N-bromosuccinimide (3.57 g, 20 mmol) followed by benzoyl peroxide (463 mg, 1.9 mmol). The resulting solution was heated at reflux overnight, and then diluted with methylene chloride. The mixture was washed with brine, dried on MgSO4, and concentrated. The resulting colorless oil was purified by chromatography on silica gel (Hexane/ethyl acetate 9/1) to afford a colorless oil (2.5 g, 56%). The resulting solution was heated at reflux overnight The mixture was washed with brine dried on MgSO4 concentrated The resulting colorless oil was purified by chromatography on silica gel (Hexane/ethyl acetate 9/1)
