Procedure

To a solution of 4-(1-bromoethyl)benzoic acid (50.7 mg, 0.221 mmol) in methylene chloride (4.0 mL, 62 mmol) was added 2.0 M of oxalyl chloride in methylene chloride (0.25 mL) followed by 3 drops of N,N-dimethylformamide. The reaction mixture was stirred at room temperature for one hour, and then evaporated in vacuo to remove dichloromethane and excess oxalyl chloride. The crude product was carried forward without purification.
