実験手順

3-ethoxy-4-methoxybenzoic acid (5 g, 25.5 mmol) was added to a solution of CH2Cl2 (40 mL) and benzene (20 mL) in a flame-dried 150 mL round bottom flask. Anhydrous DMF (9 drops) was added and the solution was cooled on ice. Oxalyl chloride (11 mL, 128 mmol) was added dropwise, and the reaction was then allowed to warm to RT. The reaction was stirred at RT for 90 minutes, then concentrated in vacuo yield an off-white solid. The solid was placed on a high-vacuum line for 2 hours, and then taken onto the next step without further characterization.
