Reaction Steps

5-Chloroindole-2-carboxylic acid (59 mg, 0.30 mmol) was suspended in dichloromethane (10 mL). Oxalyl chloride (41 μL, 0.45 mmol) and N,N-dimethylformamide (5 μL) were added, and the reaction mixture was stirred at 25° C. for 1 hour. The mixture was concentrated, and the residue was dried under high vacuum to provide the crude product which was used without additional purification.
