Procedure

4-Benzyloxybenzoic acid (15.0 g, 65.72 mmol) in dichloromethane (150 mL) and dimethylformamide (0.75 mL) was cooled to 0° C. After 30 minutes, the mixture was treated with neat oxalyl chloride (11.5 mL, 131.44 mmol) dropwise over 25 minutes. The resulting mixture was stirred at room temperature for 120 minutes followed by evaporation of solvent under reduced pressure to provide the title compound as a light yellow solid (18.2 g, 112% yield). 1HNMR (300 MHz, CDCl3) δ 7.03 (d, 2H, J=8.9 Hz), 7.23-7.43 (m, 5H), 8.07 (d, 2H, J=8.9 Hz).
