Reaction Steps

Oxalyl chloride (2.29 mmol, 0.20 mL) was added to a solution of 6-(trifluoromethyl)benzo[b]thiophene-2-carboxylic acid (2.03 mmol, 500 mg) CH2Cl2 (15 mL). DMF (15 μL) was added and the resulting mixture was stirred for 4 h at room temperature. The resulting solution was concentrated to yield 6-(trifluoromethyl)benzo[b]thiophene-2-carbonyl chloride, which was used in the next step without purification.
