실험 절차

Oxalyl chloride (1.739 g, 1.20 ml, 13.7 mmol) was added dropwise to a solution of 3-bromo-4-fluorobenzoic acid (0.600 mg, 2.74 mmol) and dichloromethane (9 ml). N,N-Dimethylformamide (1 drop) was added and the colorless solution stirred at rt for 1 h. The solution was concentrated to afford 3-bromo-4-fluorobenzoyl chloride an off-white solid which was used directed without purification.
