Reaction Steps
To a chilled solution of 5-chlorothiophene-2-carboxylic acid (0.16 g, 1.0 mmol) in EtOAc (3 mL) and DMF (1 drop) was added neat oxalyl chloride (92 μL, 1.05 mmol). The reaction mixture was stirred cold for 2 hr and concentrated in vacuo to give crude 5-chlorothiophene-2-carbonyl chloride.
