실험 절차

Next, a solution of indole-3-carbonyl chloride was prepared. A well-stirred suspension of indole-3-carboxylic acid (67.7 mg, 0.42 mmol) in dry DCM (2 ml) containing a small amount of dimethylformamide (DMF) (20 μL) was treated with oxalyl chloride (0.84 mmol, 107 mg, 72 μL) at 0° C. Following addition to the oxalyl chloride, the mixture was stirred for 20 minutes at 23° C., producing a clear, slightly yellow solution. This solution was evaporated to dryness in vacuo at 0.1 Torr to ensure removal of excess oxalyl chloride, and was subsequently re-dissolved in 2 ml of dry DCM.
