Reaction Steps

1-Ethyl-6-methoxy-1H-indole-3-carboxylic acid (250 mg, 1.14 mmol) was suspended in a solution of CH2Cl2 (12.5 mL) and DMF (10 μL). Oxalyl chloride (230 μL, 2.64 mmol) was added, and the reaction mixture was stirred for 1 hour at room temperature. This mixture was then slowly poured into a rapidly stirring solution of concentrated NH4OH (5 mL). This was then partitioned in H2O and EtOAc. The residue from the ethyl acetate layer was triturated with acetone to yield 1-ethyl-6-methoxy-1H-indole-3-carboxamide (134 mg, 54%) as a white solid.
