Versuchsvorschrift

To a solution of 6-benzoxyindole (1.05 g, 4.7 mmol) in ether (8 mL) is added oxalyl chloride (0.45 mL) at 0˜5° C., stirred for 2 hrs. The reaction mixture is cooled to −78° C., sodium methoxide (25% w/w in methanol, 2.4 mL) is added, warmed up to room temperature, quenched by water. Solid product is collected by filtration, washed by water and dried under vacuum.
