methyl 2-(1H-indol-5-yloxy)acetate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Prepared analogously to Component V by alkylation of methyl (1H-indol-5-yloxy)-acetate with N-tert-butoxycarbonyl-4,4-dimethyl-[1,2,3]oxathiazinane-2,2-dioxide and subsequent cleaving of the acid protecting group. Prepared analogously

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A suspension of 5-hydroxyindole (5.00 g; 37.6 mmol), caesium carbonate (26.9 g, 82.6 mmol) and ethyl bromoacetate (4.60 g, 30.0 mmol) in 100 ml acetone is stirred for 18 hours at ambient temperature. Then the reaction mixture is combined with water and DCM. The phases are separated and the aqueous phase is extracted with DCM. The combined phases are dried on sodium sulphate and freed from the solvent in vacuo. The phases are separated the aqueous phase is extracted with DCM The combined phases are dried on sodium sulphate
