Reaction Steps

A mixture of 6-cyano-naphthalene-2-carboxylic acid (250.00 mg, 1.27 mmol), thionyl chloride (15 mL), and a few drops of DMF was refluxed for two hours under a condenser equipped with a drying tube containing anhydrous calcium sulfate. The thionyl chloride was then removed by high vacuum distillation, yielding a quantitative yield of a yellow solid. This material was not characterized, and was carried on without further purification.
