Methyl iodide → Methyl α-propoxy-1H-indole-5-propanoate

Participants

Reaction Steps

Crude rac-3-(1H-indol-5-yl)-2-propoxy-propionic acid was dissolved in 5 ml N,N-dimethylformamide, 0.54 g of sodium hydrogencarbonate was added followed by 0.32 nm of methyl iodide. The mixture was stirred at r.t. for 7 hours, then poured into ice water and extracted 3 times with ethyl acetate; after drying over MgSO4 and evaporation, the crude product was purified by chromatograph) (silicagel, eluent: gradient of n-heptane/ethyl acetate) to yield 0.47 g of rac-3-(1H-indol-5-yl)-2-propoxy-propionic acid methyl ester as light yellow oil.
