Versuchsvorschrift
To a solution of 5-methoxyindole (10.00 g, 67.95 mmol) in diethylether (200 mL), oxalyl chloride (7.79 mL, 88.33 mmol) was added at 0° C. After stirring at rt for 3 h, the solid was filtered off and washed with cold diethylether to yield 2-(5-methoxy-1H-indol-3-yl)-2-oxoacetyl chloride as a orange solid which was used as such in the next step. LC-MS conditions B: tR=0.46 min, no ionization.
